I've seen here locally, I was bothered by it by for a second, maybe because I wasn't attracted to her, but then remembered not everything is about me. I'm sure there are people who are into it, and if RM allows it then I'm OK with it.
I had never been (knowingly) attracted to a trans-man or woman before but there was this FTM a few weeks ago in LA I think, that wow, he was gorgeous.
