It's because they're talking about it openly maybe that freaks you out a bit...but believe me, it happens all the time, other guys play mind games and string girls along, have one night stands, lie, cheat etc...is that any better (I think not myself)?? This sounds mostly like a way of confidence boosting, getting what you want, being successful and from what i can gather, alot of the guys are or used to be lacking confidence with women, so if this helps, then that's a good thing.
Heterosexual men and women tend to want to be attractive to the opposite sex and so I say, the more guys skilled at doing it in style and not treating girls like crap...more the better.
I know plenty of guys who could do with some lessons!
Not all girls are vulnerable naive little things who need to be romanced and promises of marriage (and yes, some may want that, so let them be that way and hope they find what they want)...as I've said before, alot of single girls my age know more than you may think, but enjoy it as much as men. Nothing wrong with adult fun if no one gets hurt
I like the fact it is an art, a skill, time and effort goes into it...the guys like Mystery, Style etc are certainly not stupid men, they sound very clever, and that's attractive in itself to anyone with a brain. Oh the sexual politics of it all lol!
