It's a subconscious thing. Their body is telling them that they want to reproduce, but society tells them that if they do, they're a slut.
Also, in my experience, they use it to judge (whether consciously or not) the motives of the men they interact with. Men that constantly stare at their body parts would only be looking for sex. Men who do not and maintain eye contact and conversation are not looking to simply hook up. At least that's the logic (players use it to their advantage).
i kno exacly what you mean, there are a lot of females who dress scantily clad and then when guys look they are all "your a f***ing pervert! ewww I can dress however I want!" yes that may be so but what people fail to understand is that the reality is if you dress like that you want some type of attention (usually but not always) and attention is what you will get. if you dress like this be prepared for people to look
i definitely dont. I have quite big boobs and I'm very conscious of them in public. they are noticeable when completely covered, I don't want to draw any more attention to them. I can't help their size and I don't want to be looked at as a girl in that way. I want respect.
