Had anal sex with my girlfriend for the first time the other night. I went nice and slow and she took it without any problem, no pain at all. I was really disappointed because I thought she wasn't going to be able to take it. She said it was her first time, but now I'm suspicious because she took it so easily. I might bring this up with her and potentially break up with her if she lied about it being her first time. Anyone else ever had anal sex and be disappointed because the girl took it so easy? I know my penis isn't huge, but at 5.3 inches girth it certainly isn't small!
