Had a gf who found out I was bicurious, and managed to talk me into "exploring my sexuality" by having a threesome with her black ex-bf.

I went into it pretty sure I was making a huge mistake and was probably gonna get cucked and humiliated. Ironically, it turned out just the opposite... me and the other other guy had a ton of chemistry and really hit it off. He focused entirely on me during the threesome, which made my gf jealous.

Afterwards she made a big deal out of it like I'd cheated on her, even though she's the one who badgered me into doing it. Then when we broke up a couple months later, I decided to get back at her by hooking up with her ex... which went so well that I eventually started outright dating the guy.
