I've a friend who's a lesbian, and we've been friends for nearly 15 years. We've never had sex or anything, we've always had a very platonic relationship... Anyway, ever since I got married, she's been obsessed with the idea of her, my husband and I being involved in a threesome, because she wants to have sex with me. (She's not really interested in having sex with a guy, although she's curious, it's been a while since she's had sex with a guy...) Point being, it's interferring with our friendship. She even has a girlfriend who's mildly annoyed about her wanting to have sex with me... I've had a couple serious sit downs with her about not wanting to go through with it... But I'm considering ending the friendship because of this.. am I wrong to do so?
