Most people in their early 20's aren't "looking" for a long term relationship or marriage. IMO, it's a time when people are having fun, finding themselves and beginning careers. The point, I believe, is this is an interracial couple, and that alone should be reason to wish them well. It may not last, there're quite young, but many relationships with people so young don't last.
In terms of their compatibility, it's always problematic to put yourself in someone else's shoes. There're many who find the idea of an interracial lover repulsive, regardless of the person's objective attractiveness. There're men with VERY varying tastes in women's bodies, even on this forum. His girlfriend may represent his ideal woman, because she has the "assets" he wants in a woman.
The couple's relationship may not last, which is understandable considering their ages. However, it's just as probable it happen because they grow apart as it is that either will be "enticed" to seek someone else.
Btw, while I'm sure it was a joke to suggest that women have high rep because of their sexiness, it's been my observation that they offer well reasoned and articulated posts at least as often as the men, and that's being gracious.
