Straight men don’t have sex with other men

I keep seeing posts on here where gay guys say « I’m having sex with a straight guy » and I’m just like… no you aren’t? If a dude’s having sex with you, it’s because he’s attracted to you, therefore he’s attracted to men, therefore he’s BY DEFINITION not straight. If a straight guy wants to have sex with another guy once, out of curiosity, I get it, that’s fine. However, if a man has sex with other men on a regular basis (which is usually the type of situation that’s being talked about in a lot of these posts) he's either gay or bi, and if he calls himself straight, he’s just in denial. Period point blank.
