I personally boil my futa attraction to one thing. I like women and the female figure in general, I like seeing them climax and enjoying themselves. I also like seeing them having sex with men on occasion, but really a Futa girl takes out the middle man (quite literally) and instead replaces hairy man ass with an attractive Female body with a penis and/or balls and/or vagina.
Like the comedian Mr. White asked his friend one day "Do you enjoy seeing only lesbian action?"
"No, sometimes I like watching them with men."
"Well do you like it when the man has a tiny flaccid penis?"
"No, I like it when men with huge throbbing cocks- ooooh..."
And everyone is a little bit gay, you have to find your own body a little attractive in the nude. Though occasionally I fantasize the futa penis is my own, just detached and hard working!
but that's just me, have some cake.
