This is 100% on the money. I slept around a bit in my youth and built a reputation for it that took a hell of a long time to get past. It wasn't until I was older and not within the same group of people that I managed to get girls interested in a relationship because the reputation always got in the way of that. Shit happens though I guess, it was pretty normal to be as promiscuous as I was in the area I grew up in, I'm not ashamed of it at all (though I would go back and tell my young self not to be so stupid.)Also, women are just as judgemental as guys when it comes to the magic number of how many people they've fucked. If a guy is in seriously high figures, instead of thinking what a massive stud he is, most women are thinking that a: he's going to cheat or b: that he sees women as disposable.
A huge turn off on both counts. So even if he is getting women every night, most are going to be a one time deal. There's a fine line between a hit with the ladies and man-whore.
