When I was 22 - 26 and dating, I had a few girlfriends I was sexualy active with and I told all 5 of them about this side of me. Everyone of them did not care at all but I also only dressed in front of one of them. I then met my SO and I told her about it she is fine and has seen me dressed a few times over the past 20 years however things have changed a bit. I want to explore going out to events, spend a couple days as a girl, go to the salon dressed up, you get the idea. Anyway this is where it starts to get uncomfortable because she doesn't want this to happen and when I was young I thought I would only be doing it around the house in "private for all of my life."
With all that being said if I knew what I know now I would have told her that you may never know, I might want to step out the door as a girl...All I can say is that I was as open as I possibly could be back then.
