Is it normal for my penis to get even larger?
I'll just get right to it. Whenever my girlfriend and I start foreplay, and I get as hard as I can, I measure 6 1/2 inches long, and 5 1/4 around. However, after prolonged foreplay and/or sex (15+ minutes), and as I approach orgasm, my penis starts going wonky. As I get closer to finishing, my penis gets even bigger, even though it's already rock-hard. I got up to 7 inches long, and 5 1/2 around, once, just before I finished. Although my girlfriend and I enjoy this odd effect, it can be bothersome sometimes, like during oral. She has a less sensitive gag reflex than normal, but when I get bigger, we have to stop and let her adjust. When doing other things, it doesn't get so much in the way like that. I was wondering whether or not this happens to other guys?
