I don’t claim to speak for all crossdressers, but I believe that an interest in men is not uncommon among those who want to pass as a woman in every way possible. What better confirmation is there that one is seen and accepted as a woman than to have a man show romantic or sexual interest?
I’ve dealt with such thoughts at times. I’ve never acted on them or even been in a sitution where I would I would have to choose to act in one way or another. I’m not homosexual. Those thoughts never cross my mind while I’m living my life as a guy. Having those thoughts is one of the reasons I keep trying to quit crossdressing.
