I've had no problems in finding interested people of all sorts of genders, roles, and sexual orientations. Since transitioning I've tried my hand at being a Domme, mostly trying out a few people who couldn't handle me. Most have been hetero or bisexual men, but I've also been Domme to a bisexual trans-girl. As a Domme, I usually prefer being addressed as 'Ma'am' or 'Miss', and sometimes 'Mistress'. But I hate when someone starts with Mistress if I don't know them. I find it very presumptuous and annoying. If I haven't claimed you, then I am not your Mistress!

And even then I don't care for it as much as 'Ma'am'.
I much rather prefer being a submissive though. I've been owned and collared by a Domme before, tried out by a Master or two, and am currently being considered by a Domme whom I'm also dating. As a submissive, I would be addressed by whatever name or title my Dominant prefers.

As far as roles go, I prefer being considered a slave, but sometimes enjoy the pet role and have been mildly interested in being a babygirl.
