My boyfriend of 10 years recently proposed. I accepted, but I don’t think I should have. He’s my best friend and I love him, but he’s very uninhibited. He’s into every type of fetish or “odd” sexual behavior there is. Exhibitionism and voyeurism, homemade porn, BDSM, urine/scat, blood, orgies—just to name a few. He wears high heels everywhere unless it’s impractical or not allowed. I am very vanilla, which I quickly realized after trying to participate in his sexual adventures, including exploring his bi-curiosity. Outside of that, we get along well, which is why we’ve been together so long. Do you think it’s OK to ask him to turn it down? I still feel guilty because when we met he was in an open relationship but cut it off to be exclusively with me.
