Hey reckless, welcome to Dream Views

I've had a few gender bending lucids myself, but what happened in mine was, I was already having a non lucid dream about being male to begin with. Then that's what made me become lucid. So I never had to actually 'make' myself change gender. But when I was a guy, it was very very vivid for me. I was able to have sex, but in the last one I had, I lost my erection, heh. I just found it very difficult to control me, my partner, AND maintain an erection. Go figure.

Oh well, good luck with yours
