Confused Urges

I know that I am heterosexual, as I am only attracted to women, but yes and here's the but now and again I get this urge to wank a man off, not just any man, but ones that are attractive in a female sort of way, sorry its hard to explain, maybe I should go back to my teens in the 1970's. There were these two ' Glam Rock bands ' and each had a guitarist who came across to me as sexy, and I used to fantasize about how big their cocks were and that I would like to see them naked and play with their cocks, and wank them til they shot their hot thick spunk over me, I had no inclination or interest for anal intercourse.

Recently though, I've had this crave about a guy ( he has to be hairless except his pubes ) bending me over and pummeling my a hole and shooting his load inside me, not just that the thought of this turns me on, its only the once that I want to do this, should I act on this urge and follow this up, this is my dilemma.
