In 10 years as a sex therapist and 20 years as a marital therapist, I've had gobs of complaints from women whose partners were too big for comfortable sex. I've only had 2 in 20 years about her partner being too small. The first woman had a vaginal laxity after childbirth (previously, he had been "just right" and the second woman had marvelous orgasms with the small man but had a mental block.
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.
Apart from the risks, penoplasty (surgical penile lengthening and girth enhancement) is the most expensive way for penile enhancement. According to About Health it ranges from $4000 up to $17000. If you are interested in surgical enhancement, we recommend reading the in-depth article on Medscape about possible surgical techniques and results.

Many manufacturers market the products as dietary supplements because the products contain natural ingredients, including vitamins and minerals. When shopping for male enhancement products, read the label carefully. You might find that the product contains the same ingredients as those found in a multivitamin. You should also look at what the product does because not all supplements promise the same thing. Some shoppers want a male enhancement supplement that increases stamina, but some men want a product that only contains natural ingredients.
