I had anal sex a few times with my boyfriend. Despite being extremely painful and not at all pleasurable, nothing went terribly wrong, and realistically I know that I'm totally fine, but I will regret that decision and worry about my gastrointestinal health for the rest of my life. I have nightmares about incontinence. I'm pretty straight-edge, and this was undeniably the worst decision regarding my bodily health I've ever made.
