Do Women really ask random guys to impregnate them?

I overseen a blog site full of women who want to get pregnant and have babies with random, decent lookin' men. They don't expect these men to marry them or support them with the child, they just want to have babies.....no I don't mean a sperm bank. These women prefer to do it the "natural" way. Wow, not to mention I hear my BF tell me that a girl from his church wants to have his babies because he has "good genes" and this made me despise this chick seriously. They want to do it the natural way also. BTW, she's only 18, me and my BF are in our mid-twenties waiting.....are people really that sick?
