Or your hot????
Well some guys are turned on by even the slightest of touches. Sometimes not even touching but just the way you smell or look. Some guys have more control over it...some don't. It really just depends on the guy....
How do you know they are turned on? Guys are very easily stimulated.
They're weird thats why!
They probably like you a lot if they get turn on
I don't know... Haha guys get turned on too easily... Theyre just wierd like that
It depends how close you are to them because some girls grind or some guys are just excited it's hormones or virgins
This is just so wrong... But its because males have a bad hormone problem, like major testosterone... So they might not think it, but they want some..... Or they like you...
