Oddly enough, and you may well be aware of this, if you're an attractive woman, guys might just find you intimidating, just because you're pretty. I know there are plenty of guys who's goal is only to find a very attractive woman, but many "normal" guys are very intimidated by a very attractive woman. If you have what you consider a "really good" photo of yourself on there as the one a guy would see when he gets a "nudge" from you (I don't know what else to call it besides a nudge... haha), he may take one look, and think to himself, 'she's outta my league'! I'm no expert, but you might want to replace your main photo with one that you feel is a little "less becoming" of you? Just a thought
