Please, the size of my penis lenght is 13cm. I want to know whether their is need for enlargement or is it enough to satisfy my woman
It sounds fine to me. Doesn't matter what the size is its how you use it that matters
13cm is on the small side, i'm average at 21cm.
It doesn't make a difference what size your penis is during sex, its all about the rhythm to bring a woman to climax. You might even be better off with a small one, some women are intimidated by bigger ones.
You'll be fine ;)
13cm is AVERAGE.
Regardless, it doesn't matter the size really anways.
I'm one of the women who would totally prefer a "non-average" 13 cm. In fact, 20+ cm penises kinda look monstruous to me. Call it intimidation. :P
