first and foremost i'm confident, but not conceited. have been told i'm handsome by random women. i'm also over 6 feet

lol, BUT i don't carry myself like god's gift and i'm usually bashful when complimented. i know different women have different tastes.
that said, i'm rarely approached, as in a woman trying to hit on me. they'll smile or seem a little more comfortable if we're on an elevator, checkout line, sitting next to in a cab or airplane. women also seem to make themselves more obviously approachable unless you're acting like a complete azzhole. might look you in the eye a little longer, smile more often, giggle at little stuff. just be more fun.
now i have dealt with some super aggressive types that will be eyefukking you from the time they see you. i had one coworker a while back we were cool but knew i wasnt available. said she gets pleasure out of making me feel uncomfortable as possible. shorty would look for any opportunity to mess with me. walking down the hall eyeballing my crotch, adjusting her clothes to show off her cleavage or thong, just to mess with me.
anyway if you're handsome, a gentleman, and not on some bullshyt approaching women is way easier. basically you have to fukk it up. but dont be flirting and not willing to take the next step. best way to make a woman mad.
