I just received a copy of Answering Your Questions about Heart Disease and Sex by Dr. Eduardo Chapunoff. And Dr. Chapunoff sent over some very interesting info to me that you (and your guy) may find interesting. Check it out:

"There is a study that found that men having three or four orgasms a week halved the risk of having a major heart attack or stroke. The benefits were attributed to the fact that sexual activity, that involves mild to moderate physical activity, are likely to have some cardiovascular protective effect.

These results were published several years ago by the University of Bristol researchers that involved 2.400 men who were tracked 10 years later to see how many had suffered serious strokes and heart attacks. It was called the Caerphilly study and it was presented at the World Stroke Congress in Melbourne."

And I'm not surprised. Sometimes going without sex for a while can make you feel like having a heart attack. But seriously—if I've ever heard a good reason to hit the sheets on a regular basis, this is it.
