Are you feeling icky? Then you need to get sticky!

In a Wilkes-Barre University study of 111 college students, psychologists asked how often people had sex, and then measured their spit. What does that have to do with anything? Well, according to this story on

Psychologists Carl Charnetski, Ph.D., and Francis Brennan, Jr., Ph.D., asked 111 college students (44 men, 67 women) their frequency of partner sex: none, less than once a week, once or twice a week, or three or more times a week.

Then the students provided saliva samples. Saliva contains immunoglobulin A (IgA), the body's first line of defense against cold viruses. The more IgA in your saliva, the less likely you are to catch colds.

The once-or-twice-a-week group had the highest levels of IgA, and enjoyed the most protection from colds. This group had 30 percent more IgA than the two groups who had less frequent sex and the group that had sex more often (too much of a good thing).

The researchers also surveyed participants about relationship duration and satisfaction. As duration and satisfaction increased, so did IgA level.

What does all this mean? Basically, dancing the horizontal mambo once or twice a week is relaxing, stimulates the immune system, and provides social support.

So fellas, next time your lady says "not tonight, I don't feel good", just inform her that a heavy dose of penis-cillin is exactly what the doctor ordered...
