Well for me it can get complicated. I mean I always prefer to bottom, but if I'm with a hot tgirl or femboy I may have the urge to top them. It's mainly a dominance thing with me. If said tgirl or femboy is submissive enough, that could draw my dominant side out.
As for topping men. I have absolutely have no desire to do so. There's just something really off putting about trying to stick my cock into a hairy man ass.
And I don't thing that giving or receiving oral should be lumped into the top or bottom category. Because when I'm with a man I'm a total bottom, but if he wants to suck my cock. Well than more power to him.
As for the positions I prefer. When I bottom I love cowgirl, because it gives the top the opportunity to suck on my cock that's sticking erect in his or her face.

I also like
rock n' roll that's a form of missionary where I have my legs on my partners shoulders. Hits my prostate just wright!

And both of these positions allow me to look into my partners eyes and to kiss them.
As for when I'm topping (feminine people only!

). I like doggy and missionary.
Also, it's a bit disheartening to find out that a lot of the men responding here would prefer to bottom. Is that the only reason you can muster that would give you reason to be with a trans girl?
