My situation is a bit different because I'm bisexual.
I had relationships with men and women before I met DH but nothing longer than a few months and I wasn't out to my family. I'm still not, there doesn't seem much point.
I met DH 12 years ago and thought he was 'the one' and in many ways I still do. He knows I dated women before but we never talk about it, I think he might think I am a 'lesbian until graduation' or was just fooling about, I was young. I don't want to talk about it because I think its a bit rude. I wouldn't like it if he came home one day and said " I know your not blonde but I used to date a lot of blondes and since we've been together I've had a few blonde crushes and sometimes fantasize about blondes, sometimes when I meet a blonde I wonder what my life would have turned out like if married her instead of you". Its just awkward to mention it without sounding like I'm going to cheat and I'm asking for permission.
I'm not one of those women who thinks it doesn't count if its a woman. You can't shag someone and then the next day call it something else. I don't think I will ever cheat, I'm just not the type, but that does leave me thinking that 1998 was the last time I was with a woman and it breaks my heart (Maybe not my heart exactly but ykwim).
Sometimes I think I had to pick a gender and go with it and I picked men (or man at least) because I could have a conventional life, I could have dcs, I wouldn't have to explain myself over and over. I hope I didn't, I hope I picked DH because he is wonderful and kind and funny and sexy. We do have a good sex life but it is different and that is the problem I face.
I want to be with a woman (not a specific one right now but there have been a few in the past) but I value my relationship with DH, I know I can't cheat without at least one out of the three of us getting hurt even if it is only me, I don't want a one night stand, I don't want to leave DH, I don't want to never be with a woman again. I think I might be greedy. I don't think if I was straight I would think about other men and hand wring over only shagging DH.
I want to be in sliding doors but instead of cheating knobend vs soulmate I want DH and helen mirren a woman.
Sorry for the hijack. I'm not coming out because I'm not going to leave DH so coming out wouldn't achieve anything but it has been therapeutic to write this down.
