I [21F, bisexual], decided to hookup with this guy [23M, bisexual], he got me flowers and was incredibly sweet to me. He tried to surpass a boundary of mine during sex. He tried to shove my head on his bare genetilia when I had explicitly stated I wouldn't go down raw. I stopped him from doing that and he disappointedly wore a condom. We had to stop mid sex because i was having an anxiety relapse (due to past SA trauma).I felt bad and later offered to go down on him but he said it ain't worth it with a condom. (Could be guilt tripping, not sure). He opened up about his personal life to me and said we were friends but then after that encounter, he never spoke to me again. I feel hurt. Why would he do that?
