Why are you suddenly interested in white guys and Hispanics? This sounds like another case of black women using non-black guys as a fallback plan. Yes, black guys are dating other races of women, but they do so out of genuine attraction, not because they can't find a black woman to be with.
Congratulations for joining. I don't think you have a problem; you are an attractive-enough young lady although you'd be considerably more attractive without the lip piercing. The best thing you can do is this: be yourself, but, at the same time, act mature and responsible. If you look and act like a responsible, mature person, then you will be taken seriously and respected and that is actually a turn-on to guys north of 27.
Depends, do you get jealous around their friends? Better to crack a few eggs and not care about the results. I have a client that so happens to like dark chocolate, without the nuts. I like all kinds of women too, sadly not all of them are ready for the craziness within me.
Like you would with any other guy, i mean im mexican and im dating a russian, she is pale as sugar and im, well im actually pretty white for a mexican, but its not like you have yo act dress or talk different just because of it, just be confident about yourself and that's it, guys are a lot like girls, we like confidence
