I have to say that I am currently in the most interesting of situations. I currently find myself Asexual and Aromantic unable to get turned up, horny, attracted to anyone, or even able to orgasm, yet I want to have penetrative sex. In fact when I explore solo, though I don't get off...I want to be "topped". I don't know if I would like it and I just don't want to do it with anyone, but I have this slightly want to do it. I also don't want to take a risk on a partner because of possible backlash of being trans. It is very very....interesting.
Maybe what you feel is just curiosity. When I began my transition I wonder how dating and having sex with a man would feel like. I tried really hard to give men a chance, but I couldn't find a single one that seemed attractive to me. I still wonder how it feels like, but I have no need to do it. I don't even find the thought if sex with a man exciting. There's no difference between that and trying a new icecream flavour, just to see what it tastes like to me.
