i think it does, to an extent. when i started dating my wife 5 yrs ago, she said i was alot larger than the few guys before me and was not used to it and hurt the first time i went in (girth) and hurt when i'd go all the way in (length) but after about the 5th time we had sex, it felt "sooo much better" going in than the previous bf's and felt "sooo good" that i could go in farther than shes had before. BUT, we went and bought some toys, one being a dildo that was a lil over .5" longer than me and wider than me and she did not enjoy it because it stretched her and hit her cervix harder than i do....that aside, my wife says she absolutely loves the size of my penis (only been doing pe for a few days, not even a week) but will support me in my effort to become slightly larger regardless...so in "our" opinion, average is better than small, "above average" CAN be better than average, and BIG just hurts....
