I have a lot of dreams about masturbation, and I always have male equipment, or I've just discovered that I do and I'm so damn ecsastic. Then I have to wake up.
I'm male, and I actually have trans-related dreams a lot; about people finding out, and accepting me anyway. At the beginning of transition, I had dreams that I was trying to keep people from finding out, but now they generally don't, or I tell them myself. Seems I'm a little more confident about that.
I haven't had a dream with me as female in it for a long time now, but I think... In some of my nightmares, I am. It depends on the type. I vaguely remember one in which I was crying in agony, and I remember having long hair. That wasn't a very clear dream, though. So, although it's rather vague, I'll have to echo the always male except with some nightmares. It's very strange.
