WHOA. Run from this type of chick. I've NEVER had a woman insist that I raw dog her. Any woman that does, without at least saying that she's on the pill to let you know she's protected against pregnancy (which of course is least of your concerns, and should be the least of HER concerns also), is HIGHLY SUSPECT. At minimum, she may be trying to trap you, and at most, she's extremely reckless. There could be all kinds of organisms growing inside her, and it would be reckless on your part to put your dick in there. Like Eddie Murphy joked about, she could have an STD so powerful that your dick just explodes when exposed to it!
"The best kind of pride is that which compels a man to do his best when no one is watching."
