I’m attracted to my coworker who’s a teacher but I don't know if he’s gay?

He’s a nerdy math teacher and he dresses like a typical guy. He is very skinny so he wears skinny jeans here and there but it looks nice not feminine at all

he talks a bit nerdy… doesn’t sound macho.. he’s into sports and is a sports commentator

we have a lot in common… went to the same college… from the same state ect…

he’s not gay like “hey girl “ or has feminine hand gestures.

but I don't know
