I always hear on this site, from women, that size doesn’t matter. However, I have heard maybe 4 or 5 times in my middle aged life, when a friend or member of our social group is has been mentioned as hung, the women have suddenly sprung to attention. Not in an, oh she looks interested way, but they say ”oh now I’m interested” , sometimes in front of their partners and once an ex of mine. The subject was changed pretty quickly by the men so never went any further.
Another experience: A friend of mine, very hung but not great looking had slept with a very attractive girl at his work. She would always contact him when drunk. He confided in a female friend at work what was going on and she said that it’s probably because of your size (he had slept with a couple of girls at work and this was the first he had heard of his reputation). He was very shy and extremely embarrassed.
Now there aren’t some fantasy stories, but true life experiences. I find it hard to believe that size is not something that is a huge factor, albeit only one factor in sexual attraction.
Any why is it a factor, I imagine partly just from an aesthetic point of few and probably because a big fat cock used properly hits nerve endings that a normal one doesn’t.
