Looks like sex drive comes down to genetics.

Like Chris Rock says, "No its not"  This morning I am walking the dog, its a nice mild, sunny morning.  A young, slim blonde with a bouncy pony tail is coming the other way with a puppy. She has on a tie dye tank top, no bra, khaki shorts.  Very friendly, pretty smile, we chat about the pups.

I go home, have another cup of coffee and start looking in my little black book.
