wow this gets asked a lot. lol
the simple answer is that a majority of american white guys, specifically in that age category and maybe mine as well, either don't like black girls or don't admit to liking us. having said that, there are many who do and openly express that or have asked black girls out, dated them, etc. whether or not those end up being the guys you want is another story. some of my friends have done it. I haven't but that's another story. lol
the reasons behind this are varied. it has to do with racism in beauty standards dating back through centuries in stating european dominance. it has to do with general cultural differences in what beauty is. it has to do with familiarity and differences, and whether someone finds it exotic and interesting or a total turn off to stray away from (or stick with, in some cases) what they were raised around or used to. it has to do with the fact that we look so different in some ways like our hair for example. it has to do with ignorance and stereotypes as well. it has to do with historical degradation of the black woman. blah blabby blah really talking about this makes for good discussion but if you just want the short and sweet of it all, there's really no point as far as what you're concerned about.
youre young though. don't dwell on this because I'm telling you from what I've seen online...do not go around searching for this. some of the stuff I've read can be really brutal. if you're really looking for opinions...theres some question here like "what race are you least attracted to?" asked by eddymetal I think. it shows exactly how a lot of white guys feel about black girls. a lot of white guys don't feel that way, but I think its really important that you are aware of these perceptions as a black girl. that is, if you can handle it. if you feel your self esteem crumbling right now then don't look that question up. either way, take what you read and move on. our realities that we experience online can be drastically different from real life depending on where you're from.
