I honestly have no idea what it is, if it's society, if it's internal, no idea, but I'm absolutely 100% not aroused by men at all, and just knowing a m2f transgender person once had the biological parts of a man is enough to kill any arousal that could have been.

Not that it's a common question, but my "answer" to "could I ever date/sleep with a transgender person" is "I'm not mature enough to be comfortable with that." I blame myself in some way, but I am "repulsed" by the idea (not repulsed by the person, just the thought of intercourse)

I hope it doesn't need to be said, but just to be sure: I want everyone to be able to live their best life and to be happy and accepted, I have no hate for transgender people or anyone (except billlionares, private insurance companies and maybe some landlords)
