Okay. So I met a guy and we went from a sexual relationship to a romantic one. He is married, but his wife is bisexual, and she has a boyfriend who lives with them. So he and I have been sleeping together for about a year and a half.

I’ve always identified as straight. I’ve only been with men. I’ve never even had a thought about another woman.

However, the guy I’m seeing has brought up the possibility of us having a threesome. At first I was thinking no way…but then I went to grab a few drinks and some food with his wife, and I wanted to kiss her. So I did. And I LIKED it.

So her husband told me she told him about the kiss, how she liked it and thinks I’m very attractive etc. and he said she should invite me over to their house and hook up. I kind of want to do that…but…

What if I freeze? What if I can’t go down on her? For some reason I am attracted to her now, which is so odd considering how I’ve never been attracted to women prior to her.

Am I possibly just attracted to the idea of her? Do I go through with a threesome? Help!
