I'm more of a casual pumper, maybe doing it a few times a month, more or less. However I have had very obvious gains. I started of quite large, my erect size being 9"x6.75". However after very casual and occasional pumping for about a year or so, my cock is now much thicker! It's still 9" long but over 8" at the base. When flaccid my cock is the same round, perhaps in fact a tiny bit bigger (at the thickest point) as it is long, just over 7". I am very happy with this and wonder how thick it could get, or would be if i pumped more often! However, I think I may need to stop as its causing problems. I noticed a while back that my cock was much tighter inside my girlfriend, it took some getting used to and had some embarrassing consequences. But i got used to it. But then my girlfriend complained it was too sore when she is on top, so we had to stop that. As i got thicker, she then during and after sex, said that her pussy was sore, she even asked me if it been doing any enlargement. I got a bit thicker again and now it seems i can't fuck her missionary, the only one that was ok was doggy, but she was still sore. and this is a girl that has several times accommodated fisting! so im at a bit of a dilemma, i love the gains ive had, and want to get bigger, but dont want to be too big for my gf! Has anyone else has similar gains and similar problems? btw, i'll put up a new pic soon in case you think im BS. the one i have is over 2 years old.
