Surgery offers the only permanent solution for enlargement of the penis. Through surgery, the penis can be visually enlarged, usually by just over an inch. The surgeon will cut the ligaments that hold the penis in its usual position, allowing the penis to descend. Weights, or stretching devices, are then used for a few months to affect a permanent increase in size. The procedure may result in scar tissue, the erection will point down, and the base of the penis will be hairy.
Approximately a third of the penis lies inside the body, beneath the pubic bone. In the lengthening surgery, called phalloplasty, the suspensory ligament above the penis is released, which causes the penis to extend further outside the body. This is done through a small incision in the pubic area and will be covered by pubic hair. Although this procedure will result in erections that point downward, this will not interfere with normal function.

That’s usually because they’re not getting enough blood flow to the penis, which could be the result of being overweight, smoking, increased cholesterol, high blood pressure, diabetes, or cardiovascular disease. So the first step in your penis-growing experiment should be to get the rest of your body healthy — especially your cardiovascular system. “What’s good for the heart is good for the penis,” says Fisch.

Kegel exercises are known to be highly effective for women’s health and men with prostate or bladder problems. However, little do most men know that  these can help enhance their sexual performance! Kegels have been known to be  extremely effective in helping men maintain and control erection. Just being able to control erection can also be a factor in making the cock look larger. Here are the steps on how to perform a kegel exercise.


Well my husband might not be too happy that i am going to publish this, but he is living proof that it is possible to increase penis size! It was something he was always ashamed of and it gave him incredible anxiety, especially when we first started dating. He wanted to commit to surgery but I convinced him otherwise because of the health risks. Instead, he did a lot of online research into natural enlargement methods that ended up working much better than we could have imagined. This is what WORKED for him and so you can also do it too:

The challenge was how to properly extract the tissue and also how to resolve three related problems. For a number of years some plastic surgeons performed “fat grafts” as a technique for penile enhancement. However, such approaches were known to eventually deteriorate into a clumpy, unhealthy form. Additionally, the body tended to reabsorb the bulk of that implanted tissue causing a loss of increased size. Finally, the technique offered no opportunity to increase penile length – a common patient request with augmentation.


Plenty of guys are questioning if there is a real regular proportion of a “substantial” penile; in fact, there truly are no typical male organ dimensions. The average male body size ordinarily runs from 5 to 7 INS. Nevertheless, lots of guys are nevertheless aware of the magnitude and expansion of these penises. Typically, it is just about the points they can show off to their plans associates as well as other young ladies. How to increase penis size 2018? Ways to make your dick bigger.
If these scientific facts do not change your feelings, consider the fact that maybe, like a woman bombarded by photoshopped images of "vixens" who have been surgically enhanced, you may also be comparing yourself to some unreality and suffering needlessly as a result. In fact, one 2005 study appearing in the journal Urology found exactly this to be the case. Of 92 patients who complained of a short penis, almost all of them had “overestimated the normal penile size,” noted the authors. More importantly, not one of these men actually had short penises.
The FDA is giving "Time Out" capsules a real time out. The agency says the product marketed as "100%" natural is really just a Viagra rip off in disguise. The agency says the pills contain "hydroxythiohomosildenafil, a chemical similar to sildenafil, the active ingredient in Viagra. Like sildenafil, this chemical may interact with prescription drugs such as nitrates, including nitroglycerin, and cause dangerously low blood pressure."
Though generously endowed by nature and confident enough in his body to have appeared in some adult films in his 20s, O’Connor decided to enhance his girth in 2013. “It was just something I fancied,” he says with a shrug. “Some men have hair transplants or belly tucks. I wanted a truncheon in my pants. My whole life I’ve enjoyed impressing women; this was just an extension of that. You could call it a gentlemanly thing to do.”
Last but not least, the biggest problem of a small penis isn’t the penis itself, but the guy attached to it. Every penis is different and unique, you can have a wonderful and sexually fulfilled life even if your size is below average. Always keep in mind that the majority of sexual stimulation a women feels during intercourse comes from her clit, not her vagina. Additionally, there is much more about being a man than the size of what you are carrying around between your legs. That’s probably the most important and valuable advice we can give: Try to relax, a large penis doesn’t automatically or magically make you happier or more adorable for women. Don’t let your penis size control your self-esteem.
CONTEXT Penis size is a great concern for men in many cultures. Despite the great variety of methods for penile augmentation, none has gained unanimous acceptance among experts in the field. However, in this era of minimally invasive procedure, injection therapy for penile augmentation has become more popular. Here we report a case of methacrylate injection in the penis that evolved with penile deformity and sexual dysfunction. This work also reviews the investigation and management of this pathological condition. CASE REPORT A 36-year-old male sought medical care with a complaint of penile deformity and sexual dysfunction after methacrylate injection. The treatment administered was surgical removal. Satisfactory cosmetic and functional results were reached after two months. CONCLUSIONS There is a need for better structured scientific research to evaluate the outcomes and complication rates from all penile augmentation procedures.
Yes, it can, but surgery is always associated with risks, including anesthesia, wound healing deficits, pain from scars, worst case even a deformed penis or permanent erectile problems. It’s effective without a doubt, but the last resort in our opinion. For men with a real micropenis (smaller than 2.75 inch) it’s often the only solution and covered by health insurance, but only about 0.5% of all men worldwide suffer from this condition. If you are just a bit below average, the risk versus reward calculation is negative for surgical penis enlargement. Especially one problem that arises from cutting the ligaments, the erection pointing slightly downwards instead of straight forward, can become a real problem according to professor Kevan Wylie from the NHS, he said “It can make sex quite uncomfortable. You’ve got to do a lot more manoeuvring with your partner. The advantage of a 2cm (0,8 inch) gain in flaccid length is far outweighed by the loss of angle of erection.”
“Operations are very safe,” says Viel, who founded the London Centre for Aesthetic Surgery with his twin brother Maurizio. “Perhaps 95% of our patients are very happy. Where they are not, it is often to do with expectations. Some men want 10 inches when nature gave them four or five. I have to say, gently, ‘This is not possible. I am not a miracle worker.’”
Male enhancement pills are pills that claim to enhance pleasure in sex, penis or erection size, or stamina in men. The only pills that are proven to have a positive effect are prescription medicines for erectile dysfunction (like Viagra, Sildenafil, Cialis, Spedra and Levitra) or natural supplements (like yohimbine). Pills advertised online are often illegal, unregulated, and potentially dangerous.
What is the solution to understanding how to improve penile measurements? You choice! There are some different techniques. We will deal with five methods for the way to get much larger correctly. A few of these techniques provides you with an easy short-lived sizing hop, even though the past strategy will offer long-term sizing results. A few males would like to try primarily appearing larger when it genuinely matters (like before making love using your companion). Other people are right after long-term dimension results. How to increase penis size 2018? Natural male enhancement techniques.
Compared to other cosmetic procedures, breast augmentation, tummy tucks, mommy makeovers, facial fillers and the like, we hear far less about penis enhancement. Perhaps there is still significantly more stigma associated with this procedure, or perhaps it’s just not well-suited for television, but there’s simply not a lot of talk about it in almost any media, at least nothing I’m reading or on shows I’m watching, and as such, there are a lot of seemingly unanswered questions revolving around penis enhancement. For example - - How is it done? Why? 
...just as some men care about the size of women's breasts. But many (most?) men think women are as obsessed with penis size as guys are, and that's simply not true. From all the surveys of what women want in a man (and there have been quite a few), penis size is way down the list, if it appears at all. And with all due respect to women who yearn to be "filled up," I've talked with several men who have really huge, porn-star penises, and to a man, they've said their size was not a gift, but a burden, that most women take one look at their phone pole and say, "Oh, wow...but there's NO WAY that thing's going inside me."
For anyone who is fast, useless or maybe opts to watch television or hang out with all your family members who don’t?

How to make your penis bigger fast with your hands? Natural way to enlarge penis.
While all three of our proven penis enlargement techniques provide increased thickness – and that wider girth enlarges in proportion as your penis gets engorged from arousal, Morganstern offers two different procedures that provide increase in your length – and increased length occurs with both your erect and flaccid state although not in direct proportion to the longer size. Typically? Your increased length during an erect state will be roughly half the increased length you see when flaccid. Thus, if you gained two inches in length when not aroused – you could expect about an inch more size when erect.

In the last decade we have observed the raise of penis enlarger devices based on the principle of traction. This scientific foundation, used widely in modern medicine for bones and tissues, is now successfully applied to the penis. The technique consists of stretching the shaft of the penis for an extended period of time applying a progressive traction force, thus causing new cells to grow, which consequentially causes the entire penis to grow in length as well as in girth, in erected and flaccid state. The gained results are permanent.

Even technology is offering some help, let’s call it digital male enhancement, although some people may qualify it as cheating: An android app called “RetouchMe” is offering retouching services for your face and body and explicitly includes an option to virtually get a bigger dick. Sample photos only include dressed men with a big bulge in their pants. Use at your own risk and always remember, making promises you can’t keep on Tinder, Instagram or your favourite dating site may result in disappointed women and that’s not what real enlargement is about.
In Warshak's case, the government had used a retrospective process to gain access to prospective messages. The SCA does allow the government to issue "preservation" requests, but these apply only to existing records that might be at risk of deletion; they do not apply to future messages. The Department of Justice's own surveillance manual made this clear even at the time, reminding agents that preservation requests "have no prospective effect....[Preservation] letters can order a provider to preserve records that have already been created, but cannot order providers to preserve records not yet made."
And speaking of reconstructive surgery, this is a huge risk as well.  I'm not qualified to speak knowledgeably about this topic.  But my understanding is this kind of surgery is usually only an option for medical need.  Completely non-functioning penis, reconstruction after serious injury, sex changes, that kind of thing.  If you were to do this for purely cosmetic reasons, for example because you want a bigger member, if you found a doctor who was willing to do this for you my understanding is that you'll trade this off with a loss of sensitivity.  Depending on the methods used, you could wind up with nerve damage, or even areas of no sensitivity.  And sensation is one of the major mechanisms for many men to achieve an erection.  I have heard tell of men who got such surgeries only to wind up with a larger penis that didn't perform.

[Agents] were not required, before commencing the search, to present their estimate of probable cause for detached scrutiny by a neutral magistrate. They were not compelled, during the conduct of the search itself, to observe precise limits established in advance by a specific court order. Nor were they directed, after the search had been completed, to notify the authorizing magistrate in detail of all that had been seized. In the absence of such safeguards, this Court has never sustained a search upon the sole ground that officers reasonably expected to find evidence of a particular crime and voluntarily confined their activities to the least intrusive means consistent with that end.
It starts by locating the PC muscles as we mentioned above, then you have to squeeze and release it several times, you can start with 40 times during the day, then do as many as you can per day until you reach the goal of 250-400 times per day. What is good in this simple exercise is that you can do it anywhere, in the house or the office for example and no one would notice.
The surgical treatments, the researchers found, were dangerous and had “unacceptably high rate of complications.” But among the nonsurgical methods, at least one appeared to help grow a man’s member: the “traction method,” in which a penile extender stretched the phallus daily, resulted in average growth of 0.7 in., or 1.8 cm, of the flaccid penis in one study. In another study of the same method, men reported an average increase of 0.9 in. (2.3 cm) in length while flaccid and 0.67 in. (1.7 cm) while erect.

Agree with Mary. Most women I've dated have stated they only date men with big dicks (7and up and fat). To many, 7 inches is their minimum. Most women may not have this criterea but many modern women do. Saying penis size doesn't matter is a ridiculous PC answer. However, vaginas come in different sizes. A big dick with a small vagina is not meant to be. The Kama Sutras recommendations in this regard are far more helpful than just denying it matters. It matters... To some women... To varying degrees. Key is in finding partners who are a good mutual fit.

I ask for his pre-op dimensions. He doesn’t want his exact measurements reported, but they are surprising: while flaccid, he was smaller than most men; erect, his penis grew significantly. Modecai, it seems, experienced two decades of stress despite the fact that, fully extended, he was bigger than the UK average. This apparent contradiction does not surprise Angela Gregory, a psychosexual therapist based at Nottingham University Hospitals NHS Trust. “Penis enlargements can be about a lot of things,” she says. “But the amount of anxiety a man experiences rarely, in my experience, correlates with his actual size.”
It's not clear if "Stiff Nights" is a "dietary supplement" as its maker claims, or a bad b-movie title, but in either case the FDA says men looking to "regain the thunder" should stay clear because the pill really contains sulfoaildenafil, an untested chemical similar to the active ingredient in Viagra, which can interact badly with nitrates and cause low blood pressure.
