I have a pretty extreme curve that I’ll be working on. I’m not sure if it’ll work but I have a pretty good idea of how it started. When I was about in 1st grade elementary school I found out that I could achieve orgasm through grinding my flaccid penis on hard surfaces. Now many years later I’ve got a massive downwards curve and my dick actually points downwards.
Anyway, it seems that to make structural changes the best technique is to go from flaccid to hard, and that’s what I’ll be trying.
