What actually causes a woman to feel loose? Are some women born just looser than others? Does this happen from sex with large partners or could it just be the case? I ask this being I have had bother very tight and loose women and I wonder what it could be. The most recent loose one had a very small history of only two others and she claims I was thicker (not longer) than all. I ended up causing pain to her but it was probably because I can have marathon sex and I guess that wore her out. She claimed to feel my girth as soon as I went in but to me it was a little loser than the other most recent I had. It wasn't so bad as there was definately friction but I just wonder what peoples thoughts are on this.
