"Imperilled" is a word in ENGLISH

We'd walk home together in the foggy summer night and I'd tell her about sex; the good stuff, like how it could be warm and exciting--it took you away--and the not-so-good things, like how once you showed someone that part of yourself, you had to trust them one thousand percent and anything could happen. Someone you thought you knew could change and suddenly not want you, suddenly decide you made a better story than a girlfriend. Or how sometimes you might think you wanted to do it and then halfway through or afterward realize no, you just wanted the company, really; you wanted someone to choose you, and the sex part itself was like a trade-off, something you felt like you had to give to get the other part. I'd tell her that and help her decide. I'd be a friend.
