For years and years before I knew anything about the subject of being transgender, I thought I was a lesbian trapped in a man's body, I kid you not. Never heard of that ever before, but plucked it out of my own mind. I've been experimentally intimate with a couple different guys, and while I never got aroused by servicing them, I never got aroused by servicing women either, weird? And I definitely am not attracted to the bigger, tan, hairy men, but instead, the ones that are more androgynous used to turn my head. ;-) when I got married though, I shut down all those feelings so I could live the life I was "supposed to".
Now, me and my wife's sex life has been dwindling over the years, and we haven't successfully had sex in the last 5 months, and only tried I think twice at that. Part of that is due to my having MS and how it's affected my ability to perform, but I haven't really WANTED to be with her either in nearly a year I think, except for the purpose of trying to conceive a child, which we succeeded at about 5 months ago.
Anyways, back on topic, I've becoming more asexual and non -sexual in the months leading up to my self-discovery about being transgender and I wonder if it's related. Nothing turns me on anymore, not even porn. The only time I get "excited" is when things make me genuinely happy, and of course the overnight automatic ones still show up every now and again...
Can't wait to see if hormones change things in this area. :-)
