Social pressure....for sure.
I'm male...my thoughts have always been...if your a guy you can f**k as many women as you want, get a chick pregnant, nothing really happens, you might pay baby support but you just move on if you want.
Girl gets pregnant SHE has the ultimate responsibility for the k i d.
My advice for women, mess around all you want, with whoever you want, enjoy however you have fun just don't get pregnant. Looking back, you may regret some decisions (guys you've been with?) but you just move on.
I've known many women with "little trophies" they've brought home. I stayed away from those girls.
Say your a cuck couple, with a young family, you do this on the sly, motels, bull's place, wherever. It's an exciting, exotic thing watching her with a hot black guy, hubby and wife both get off with it. She loves it, hubby loves it, all good. If something should happen, she gets pregnant...how in the world do you explain one offspring at 8 years old, another at 5 years old...then a biracial at 3 years old ???
Damn...have fun however you like just don't get pregnant.
