Personally, I'm bi/panromantic grayheterosexual. It sounds more complicated than it is, basically I can be romantically attracted to anyone, and I'm mainly sexually attracted to women (but graysexual, similar to asexual, means that I don't feel extreme sexual attraction or the need for sexual acts). However, I am attracted to FtMs and some other genderqueer people.
I think in terms of sexual attraction or the desire for sex with someone, it depends mostly on what the sex would be, so basically it would depend on their genitals, but I can still feel attracted to anyone regardless of what they have, who they are, or their gender.
