Is it normal for a gay man to get sick at the smell of pussy?

So I gave this gay guy friend who’s really good looking and I was making like I wanted him to fuck me. And he told me that he took a girl out once because his mother insisted and they were making out and he slid his finger in her pussy and smelled it just to see what it smelled like and he nearly threw up. I know now he wouldn’t but I didn’t know gays can’t stand pussy that much.
