Apples and Oranges: Get One And...

I was talking with a friend of mine last night about the mechanics of guys getting laid in social circles, versus the mechanics of girls doing the same. He's one of those guys that the community would call a "natural". We concluded the following:

If you're a guy and you sleep with one girl in a social circle, it gets easier to sleep with all the rest of the girls.

If you're a girl and you sleep with one guy in a social circle, it gets harder to sleep with the rest of the guys.

As he put it, "The more girls who know about your exploits without knowing names and without you telling them, the easier it becomes to get sex."

As I put it, "Boys like to feel like they're special, like they're planting a flag in an unclaimed piece of territory. And once you've hooked up with one of them, his friends will pay lip service to the idea that he has some claim to you."
