Random question

So over the years I've known and become friends with a few different porn stars, and so have some friends of mine. One, a female friend, asked me one night, "When you're jerking off to porn and J**** is in a scene do you stop, or skip the scene or keep going?" I said, "I keep going. Why ruin the moment?" She said she would skip the scene. I figure, I jerked off to her stuff before we became friends, why not still.

So the question, what do you do if you see someone you know in a scene when you're jerking off?
