Me (F32) and my partner (M31) have been together for nearly 3 years and we have I think very good very open communication. We have amazing sex and overall we have a very good life together ( we live together). But a couple months ago we were drinking and talking and I don’t remember how we started talking about our sex history and my partner had told me before that he only had 3 sex partners before me which it was obviously fine with me I never asked him anything we just were talking and opening up with each other and after a while he just comes out and tells me than 2 out of those 3 partners have been men. Now I have always identified myself as straight and always have been with straight man I cannot emphasize enough that I love him so much and we have no issues but I couldn’t help but been thrown off by this information since he had never told me that before. I told him that this doesn’t change how I feel about him (because he was very worried about that) but I don’t know how to shake the feeling of confusion I have I don’t know if he is bisexual ( he says no) but I don’t understand how you can have sex with 2 men and say you are not. I don’t know what to do because now every time we have sex I’m thinking about this and I cannot help but to feel like I’ve been lied to or misinformed in our 3 years together prior to our conversation
