Doesn't really happen to me. But I'm bad at noticing things like that and there are almost no girls in my major. There's been many times where my friends have said "Didn't you see that girl was eyeing you up?" and I had no idea. But yeah everyone likes to feel desired, guys included. It makes me feel like a million bucks.
I confess that I kind of look away to if I get caught. I'm not that great with eye contact. I wouldn't mind at all if girls were staring at me but I never really knew how girls felt about it. Does it make them feel wanted too or does it make them uncomfortable? I don't really obviously stare at their boobs or anything just at them in general. Sometimes I just stare off into space and they think I'm staring at something or someone. If I walk by a pretty girl I'll glance over but I won't obviously turn my head. How do girls like to be looked at? What do their responses to eye contact mean?
