If you don't pop a boner whilst watching this, then I suggest you seek medical attention because something might be wrong with your plumbing. If your doctor is a hot single man, that could be a great icebreaker: "I was watching this incredibly hot porn flick where the two studs ended up in a standing fuck." See how your doctor reacts; he might be able to help you with your pecker problem in a manner you did not originally anticipate.
