I like the feminine aesthetic and on the level of initial attraction if I'm into her I'm into her. I've seen plenty of trans women who I find hot. But that's all theory. In practice, I've never been in that position so I can't honestly say I would be fully down. Maybe I'd be uncomfortable. I don't really know or care what that makes me, but to your question it's not a firm no I guess. People should be able to fuck whoever they find fuckable and not worry about perception
