I noticed myself that recently I started to somewhat prefer (trans) women with penises. Not to a degree where I cannot get off to women with vaginas, and in fact I still like both kind of genitalia, and otherwise personality and other stuff is still way more important for me in a relationship (or would be if it wasn’t so unreachable for me at the moment). I also have an “unhealthy” obsession with anal sex, on both ends, but since almost everyone has a butt and I mostly use toys, I don’t really see the lack of a penis a great disadvantage on that front (also I’m a bit of a size queen myself), and also know from many of my trans friends that most trans women don’t really like to be the penetrating one.
