there are a few guys at my old high school who seemed to run through the whole female population during my time there. so naturally I asked around and did some investigating on how they were each able to run through girls with little to no effort while managing to not be even slightly more attractive than the next guy. i asked a girl that one of the three guys had sex with and she described to me what was called the "domino effect" in which a girl has sex with a guy and then proceeds to tell her friends, making them inclined to "test the waters" themselves. could i get some verification on this? does this happen in college and in the real world? or is this just nonsense?
