This made me remember a time back in college where I had a roommate who was absolutely terrified some girl his buddy knew was going to accuse him of rape. Hooked up with her at one of our parties, got her into bed and at some point several minutes into sex she said "hold on a sec" while he was thrustin' away. At which point she got up, got her clothes back on and fucking RAN out. He never heard from that girl again, but he was scared shitless for several weeks. All it takes is for a girl to regret the decision, to tell you to stop right in the middle of the act before you can get a chance to react and stop, and your life is potentially ruined.
