The number of sexual partners a woman has had doesn't say a whole lot about how "perfect" she is. Mind you, a truly excessive quantity is probably a symptom of some other issues, but I've never met a woman that expected the guy to be a virgin either. And I personally don't have any insecurities that would make me demand virginity from a women.
If you are measuring "perfect" as an inverse function of how many sexual partners someone has had, that is pretty much missing the point. I would prefer an exceptional woman who has been with a number of other guys than a brain-dead boat anchor of a virgin.
In the big picture, long-term scheme of things, minor statistical deviations with respect to sexual experience are largely inconsequential (though I guess virginity would be a statistical deviation).
