HELP(Maybe Tmi)

Im in a very happy relationship with a transgender. Girl to guy. And well, we were making out and he fingered me and it was all good and very enjoyable. But, I don't know if I should touch him down there..? Like is it a sensitive subject? He wants to be a guy but he hasn't had the surgery so he still has a vagina. Im very confused, and have Alot if questions.. And one more for today anyone know any tricks for getting rid of hickeys FAST?
