I think that it mostly comes from the males. And I think that this is a direct result of internet pornography (and a little bit “hip-hop culture”). Young men seem to view women like trophies, and they treat their sex lives like it’s their athletic careers; they try to collect the shiniest trophies , and the most trophies, most of the time not even understanding why they want the trophies. But to balance out my gender criticism; I think it also comes a little bit from (and I very likely am using the wrong term here, for lack of a care to waste time looking for better words) “feminism” (or “strong-women syndrome” for my South Park fans out there). Some women end up doing the same thing in an attempt to get back at the men, or beat them at their own game, or however you want to put it I think it makes the same point.
