Wow interesting comment, and yes jerkin off does make your penis bigger but only for the next oragasm, thats why most guys jerk before meeting a women. If you want to increase the size of your penis there is a natural way to do it. It's called Glecking or something like that, i forgot how to spell it. I've been doing it for years and it works for me Went from 7 1/2 to 8 3/4 in about 4 or 5 years, took a while but it's better than paying for it. I think it's a part of Karma Sutra. Oh Yeah, mine doesn't curve at all cuz I wank with both hands Peace
