I think there's some truth to this once you get older 30+ chances are most females would have a long string of sexual relationships, and it might also include some dark times.
I'm assuming most coli posters are players anyways, so I don't see the problem. You reap what you sow, no? Can't be hypocritical about this, you want to marry a saint even though you've pined numerous chicks? Come on now.
But I don't think it will happen to everyone, and that's kind of a positive in getting married early; less relationships in general.
