Eyes, some compliments and some forced closeness give me the get go to do so quite often. I notice it happens more when I'm well clothed and with contacts instead of glasses.
I don't like compliments or the presence of someone not close, too close. Eyes are ok, people can stare at me all they want. I don't approach, because I'm in a relationship/not emotionally available and even if I wasn't, I remember thinking of it as a hassle. I don't really want to know someone just because they're horny/attracted, there has to be something else there.
How often? It depends, eyes certainly once or twice a week, increases if I'm out a lot. Things invading my space... too much in my face, once or twice times per year, probably.
Was working the polls once and almost started a fight, because the girl I was working with got jealous when another worker said she wanted to talk with me. Later that night the one i worked with said she invited me to "Tutor her in math"
I never followed up after that day for reasons.
You did the math.
I’ve read that you get less approached when you are really attractive, as the opposite sex thinks that they won’t stand a chance with you. So I just go with this answer.
Yes, but they can't stop looking at you when that happens.
It's your choice to approach or not. In fact it's the same for them. We guys stare and they usually don't come over.
Because the conversation is awkward when it's solely based on attraction by one of the parts, I guess.
