Maybe one of you has a good idea on why some chicks always bait for compliments and validation and some just never do.

I used to associate it with how the chick perceived you. If you were perceived as sexual and attractive she'd bait for validation, otherwise she wouldn't. As of recently I noticed that although the second bit is pretty accurate, chicks won't bait you for validation if they don't perceive you as valuable/attractive, the first one isn't that accurate, some chicks simply don't bait for validation.
I'm making an assumption here. If I'm banging the chick attraction is higher than before I pick her up and she's more prone to bait for validation.

Why some chicks just never fish for validation even though they're attracted enough to fuck while most of them do it all the time?
