I have known men who needed porn to get aroused. I have heard of men, and women who need S&M type stuff to get aroused. What do you call their “orientation”, if arousal, or response, is what an orientation is.

I guess it depends on what they do with their arousal. If the porn stimulates a guy sufficient to make love to a gal, he’d be hetero. Same goes for S&M.

To answer your question in another way, the type of porn that creates arousal would be the tipoff. Gay porn wouldn’t do much for a straight. And S&M ... well, I have a hard time thinking of that as sex at all, much less what kind.
