Not to be mean but going from unexperienced and shy to experienced and confident is true for basically anything new humans, females and males alike, take up. This is a really generalizing post and in my opinion doesn't help people to deal with relationship Problems at all. You always got to look at the individual situation. And they only make sense for 25 year old women maybe. I have to agree that an unusually high number of sexual partners in both males and females can mean trouble a lot of the time but as I said it is pretty pointless to generalize like that. It makes me sad that some people would use such categories for dating. Please never forget you have a Human being in front of you and not a number. Follow your Heart but don't be naive :).
