A women's reproductive system is not considered to be an inverted mans reproductive system... IE a women's vag is not an inverted penis and the ovaries are not the ball sack!
My BIL has been claiming this. He came to a party we threw for a friend of ours ( who is single) and THIS was one of his topics! *face-palm* .... Dude is 26 yo and single.... hmmmm?
BTW ladies.. He's 26 and single, and ready to mingle =D
