I'm impressed with your answer, I must admit *Grin* I've had a lot of answers over the years, but this is a pretty good one. Most cannot explain it though.
Lol, you are male, so normally it shouldn't be that hard for a female to bring your attention back to what's supposed to be going on. But, in case it does happen, I do offer my humblest appologies
One way of dealing with it, is touching the skin of the girl and focus on the sensations and her reaction...all thoughts should fly right out the window at that point :P
