Interesting discussion. Deserves attention and thought.
A few contributions:
I think that lecock80 was spot on when he mentioned that "social value" requires definition. That's an almost meaningless phrase. Your definition, that they are more "desirable," begs the response:
Social value assigned to the more sexually experienced is not an outcome or result, but it is a predictor and prerequisite. Meaning, if you are more "desirable" you have more sex. Makes sense, doesn't it?
If I change your definition from "more desirable" to "receives more societal benefits, including respect, social status, acceptance and influence, as well as economic station," and if I stay disciplined and keep to the original point of your question (more sexual EXPERIENCE) I would say that there's no correlation at all, and if there is any it is weakly biased toward:
Women receiving less social value with more experience
Neutral for men, with wide variation according to other much stronger determinants
Determinants such as education, race, familial wealth, personal characteristics, occupation, and whom the sexual experienced is gained with -- among other factors.
It's kind of like trying to draw a conclusion as to whether someone is well dressed by studying the buttons on their blouse. Other factors predominate.
See.
And of course, if the question need be asked (or answered) at all, it suggests a possibility that we all presently need to gain some additional sexual experience -- but specifically the kind of experience where we would be distracted from any consideration of the acquisition or loss of social value.
