Been with my gf for a year or so. She is bi and I knew this before we started going out. She has only had one experience with a girl before and that was about 10 years ago, she has always said she would never date a girl but would like another experience some time. But she is perfectly happy in our relationship.
I haven't told my friends she is bi as I don't feel there is any need, and in some ways I feel it might devalue the relationship, as if I can't give her everything she wants. We are meeting up with my friends at the weekend and one of them is a lesbian, she has a new girlfriend (first one) who we have not met and she will be there when we all meet up. I've told my girlfriend they'll be there and I said that none of my friends know she is bi. She got really annoyed and said "so it's like some dirty secret is it?". I know she is going to be interested in finding out loads about my friend and her girlfriend but I really don't want this meet up to turn into a whole afternoon of talking about being a lesbian. I haven't seen these friends in ages but I feel the afternoon will be taken over by this, with my girlfriend showing more interest in chatting to them.
Am I thinking about this too much? My gf seems to think that my friends will find it really cool and be really jealous because I might someday get a threesome. But I am going out with her because I love her, I don't want to feel like she'd rather be elsewhere. I don't feel the need to blurt it out and tell my friends, and I'll be extremely annoyed if she does in front of them at the weekend.
Thoughts?
