Like what? Some hoz dress n act modestly but still got alotta bodies
Fam if you read what i said i did not just say how she dresses or behaves, but i named multiple different factors, when all these things are attentively observed you can work her out. There's only so long people can keep up pretences and females only ever do it in regards to the most obvious surface behaviour. But girls who sleep around don't have the same mindset as girls who don't for example, they don't have the same values and opinions on various things, not the same hobbies and interests, the appearance of those in their social circle is different, life experiences etc. You pay attention to those things, aswell as everything she ever tells you, the things she tells you about herself when shes not consciously trying to sell herself to you, like stories or attitudes or thoughts or opinions she shares and bits of those which reveal characteristics of her.
You don't have to ask her anything, you just treat her normally and do your thing, get to know her but your paying close attention to all these things. You will learn a whole lot more about a female and people in general from this approach then you ever would from asking them.
