Why is it worse for a girl to sleep around and settle down later in life than a guy doing the same?

I understand how several guys seemed irritated when some girls go for casual sex and then at a later age such as late 20's or early 30's want to settle down with a provider, low past type (marriage material guy basically).

However, some guys are guilty of the same thing; spending their youth going to clubbing, telling their buddies about the girls they hooked up with and pay hookers. Then, after all that fun later in life they suddenly want a nearly virginal and much younger woman to accept them and marry them. The older he gets such as late 30's, the more likely he'll increase the woman's age range (by then the woman will have a past). He can't continue going after 18-24 year-olds forever. It's gets creepy by then.

Personally, a person with high standards (man or woman) and very strict with their beliefs wouldn't accept less. They would look for a like minded partner.
