Depends on what you mean really. If we're referring to an intimate relationship, probably appearance. Under 140lbs Can't have brown eyes Good teeth At least an 8/10 face Good complexion Healthy hair 5'5"-5'10" Nice ass Brunette or blonde No piercings besides ears Good dick sucking lips but not too big Can't have a big nose Groomed eyebrows Maximum of a d-cup Nice legs but not thunder thighs Skin cant be pale, orange, or black (no offense, I'm just not into black chicks) Can't be anorexic but can't be a body builder Not too much make up Face can't be too pointed or smushed in Eyes a normal distance apart Ears can't be too big Hair past her shoulders Wears nice clothes, not some trashy shit from hot topic or something Shaved Labia can't be obnoxious Voice can't be overly high pitched, too low, or nasally Nothing out of proportion Also, I'm referring to "intimate relationship" as friends with benefits. I don't look to be "friends" with females. Either pang them down or they don't matter. If they end up having a good personality, I might coincide into an actual relationship, but that's a long shot really.
