Do men always notice when another guy is into a girl?

Let’s say you’re hanging out with a female friend and you introduce her to your other male friends: or co worker at work : do you instantly notice if one of them is into her?

Or even with strangers: for example she runs into a former coworker and they’re just talking normally: would a guy immediately pick up on it if the other dude was into her?

If yes to all of that: how can you tell?
What gives it away?

No because for men they will bang a light socket of you leave it uncovered. You can't waste your time trying to figure out which one he is interested in.

they will notice or imagine...

but they are blind if a girl is into them :D

no, I hardly pay attention to that. Most guys just want sex anyway.

Yes men do notice that.

how?

Simple by judging the kind of vibe, connection while they interact etc. The way the guy looks at the guy.
