I thought there was no way in heck I'd ever be attracted to someone with a penis. Then at around 4 months into hrt transition something started to change, and I was no longer attracted to cis females whatsoever. Honestly the only women I have been attracted to since have been trans women who happened to be pre-op.
Although I know for sure that genitalia had nothing to do with my attraction there (it was more about being attracted to someone who is absolutely sure of who they are), I definitely have found myself swooning over a few guys... and the thought of having sex with them as a woman makes me extremely interested in the penile part. I can already tell that after SRS I will have zero reservations about them.. Heck, I am pretty sure I'll be all about those "parts"

I would have NEVER guessed I would feel that way going into transition. You just never know. And with such a life altering decision to transition, it's the perfect time to not hold anything back and to let your sexuality flow with the wind!
