Ask your friends/family what they think your doing wrong or how you can spice up your look or personality. Your more likely to get a honest answer from them...................Only thing I can think of is that you come off as "needy" or "desparate" or perhaps on the opposite side......"arrogant" and "unapproachable".......................... ..Not saying you are just that some people have this natural aura about them and the rest of us gotta work at it a little(including me). :)
