Rationally there should be no problem at all as long as there is no conception.
By the way, I usually do not buy the"Oh my God there is a chance of one controlling the other" like if sex was the top of the ultra-mega-max forbidden and sacred intimate stuff existing in the face of Earth. See, people manipulate each other in a number of ways. In a sense, the TV, internet, your boss, the authorities, your parents, your mate, all of them mentally and physically are able to violate and abuse you everyday in much worse than tricking you into giving sexual pleasure or something like it.
Of course I'm not defending domination or anything here, far from it. Just trying to put things into a clearer perspective.
