There is actually no way to be absolutely and undoubtedly sure about the number of se_xual partners a person has had, but with a keen eye and an observant mindset, you can have a pretty good idea about her level of experience.
Women that find it extremely easy to talk about se_x are more likely to be se_xually experienced. More se_x usually experienced mean more se_xual confidence, especially if she is having great se_x. Once a woman is se_xually confident, she will have no qualms about discussing se_x-related issues.
She is up-front
The more se_xual experience a woman have, the more open she is about her needs. If she seems to know exactly what gets her off then she is a pro in the sheets.
She shows you a thing or two
You might consider yourself a bedroom don, but when you get in bed with her, she begins to show you explosive things your body can do that you never knew. This is because, not only has she been pleased a lot of times, she has also learned how to please.
She is brazen
Does she find it easy to take off her clothes and dance for you? Is she rocking that Cowgal move like a p0_rn star? If she seems to be very uninhibited and able to let go in the bedroom, then she is no rookie.
