good luck in the future, maybe carry backup condoms with you if you don't already. and threaten to twist their balls if they take it off at any point, unless it's to put a fresh one on. if you snarl a little when you deliver that line, they won't take it off. trust me. you just gotta be convincing. maybe get some fake prison tattoos and be vague about where you've been the past 5 years. use the word "shiv" at least once. just some thoughts.
