Do girls like when you put whip cream on their vagina?

On? Yes, no problem. IN? Probably not; you would want to be VERY careful to wash it all out. Whipped cream contains a lot of sugar, and this could aggravate a SERIOUS yeast infection. And the propellant gasses in the can of whipped cream could cause an air embolus, which can be fatal.

A little fun probably isn't worth your life.
