I think it could depend on where you fall on the TG spectrum.
If you grow up as a man it's heavily enforced that you should be the dominant partner but this may get a bit skewed if you're not interested or have negative feelings towards your parts.
Instead of dominant and submissive you could always go with top and bottom, I mean, you'd have to be okay with the gay but that's a bit less discriminatory and assumes both partners are equals.
Personally I'm not wired to be a top, I just wouldn't know how nor do I have any interest in learning but like everything else it could change.
I just don't feel comfortable with the idea, of course it may have nothing to do with being trans and I was just going to be a bottom regardless of gender identity or sexual orientation.
Take that with a grain of salt though since I've not been with either, it's all just theory to me at this point.
An interesting one though
but it certainly helps me open up and explore more by discussion.
