My observation as a woman is that straight men, those in my experience, aren't interested in touching other men, but that doesn't let that prevent them from their goal of getting into and getting off in a woman. Not so much the visual or the kinkiness, just their desire to ejaculate in her.
Guys aren't deterred by even the most masculine indicia of another man - cum. They will go right into a sloppy vagina, bum, or mouth without clean up, no problem. Something I must admit I do like.
