I'm neither a D.O. nor Licensed Massage Therapist, but I'd think that its an immune system response to the presence of foreign bodies. From a certain perspective sex is a disgusting exchange of of bacteria and other possible pathogens. The fact it occurs in the mouth and lungs would seem to support that its not the act of sex but the exchange of fluids and air during passionate kissing. If you hermetically sealed both people's heads during the act would the immunological reaction still show up? Could you get the same results if someone spit in your mouth and breathed in your face for an hour a day?

The health benefits I'm aware of for sex are more related to stress relief.

Automatic vote up for anything that says get down.

Well ... I was gonna avoid it but now that I know it has medical benefits I might give it a try.
