I was taught by the neighbor that its rude to spit ;-) And my granny always said "Never turn down a free meal" (but imagine it in really broad northern english accent)
This. Love both, and from feedback I've had there's lots of girls/women who don't like either.
Strangest I've had is a guy asked if he could cum in my hair. I was fine with that, thinking he'd lay his cockhead on my forehead and shoot on my hair that way. No, he wrapped my hair around his cock (back when my hair was longer) and stroked with it till he came.
