Anyone else is disgusted by the idea that other people have sex?

I'm not a puritan or anything like that. I understand on a conscious level other people should be able to do that if they wish, even if they're doing non-conventional stuff like having multiple partners, etc and I'm okay with that. But imagining the sexual act itself and thinking that people around me regularly do it makes me physically repulsed. Like, I feel a physical sensation of disgust right in my guts when I think of it.

What is wrong with me pals? Is it just low test?
