Hyper-masculinity turns me on (big muscles, jocks, uniforms, leather, bikers, etc…).
I am versatile. I can Top oral / Anal just about anyone (good imagination).
I'm VERY picky on who I will bottom for.
Fem is a huge turn off.
So chemistry is a huge part of my sexual orientation.
If you haven't found your chemistry I can see being confused on orientation.
Have you played with any toys? Sometimes that can help you figure out if you can get any pleasure from anal, then try to find the right partners to give you that pleasure.
