Unless the chic is a Ninja, and hops on the cock before you realize your pans are off (happened last week) I always stop the party, and wrap it up. I have condoms hidden everywhere just in case. My wallet, my pockets, all my cars, tool box, in the garage, my dresser....
Unless I am 100% confident in where that snatch has been, I dont trust it. The Hiv is the rest of your life. Sam does not follow my philosophys though...
Ok, I'll get off my soap box.
