Why do guys clear their throats when they see a hot girl?

It's kind of a pointless question, but I'm curious to details. Clear their throat OR just cough...do they do it because they want the girl to notice them? and they do it when they are alone, not just with friends. I've been noticing this a lot lately.

I believe the thing is that you guys don't even notice you do it, that's why everyone is like NO I DONT?
