They can be amazing in bed, they have a lot to prove and can cook. If you're a succussful guy with a little charm they will be washing your balls for you.
That's about all they are good for.
Oh and the majority of them like angry anal sex, if you're into that sort of thing...
Don't meet the kid! Just don't do it. Let the whore wallow in her own misery alone. NEVER ask about the kid and if they bring it up, change the subject.
Never let them stay the night, make them go home to their seed, don't give them the luxury of being away from the demon child they created. They will do anything for a night away from the spawn, don't let them have it unless they have earned it.
Finally, don't add them on FB. Pretend like they don't exist, don't let them meet your friends, etc.
Go forth and bang as many as you can, they want cock so bad they will most likely fuck on the first date.
Easy pussy brothers, pump'em and dump'em. They are used to it anyway.
