It's been hard getting laid with what i have so I really won't be losing anything by getting wider anyway (seeing i have to pay mostly). I want to be as endowed as pornstars Shane Diesel or Shorty Mac. What I would or would not get hardly matters in terms of sex seeing I'm hardly sexually active with partners anyway.
It's much like for a body builder a certain amount of mass isn't enough despite how repulsive it is lol. Body dismorphia I guess. Yeah I'll post a pic up later. Chances are I may have exaggerated the width by 1/4 of an inch or so.
What I am interested in though is whether gains are temporary or permanent and are there debilitating risks involved in some of these exercises?
Yes there are risks. You really need to read the safety first post (it's stickied) at the top of the beginner's forum. You need to warm up really well, and make sure you're not fully erect when doing some of the exercises. Ignore those two and you could seriously damage your unit. You only have one penis, so treat it well while doing PE.
