I think what diegocaleiro is saying is that these social and emotional factors are adaptations that evolved due to the biological dangers. Now that the biological dangers are mostly gone, the adaptations are unnecessary and even harmful. So inasfar as we can consciously influence the social and psychological factors, we would benefit from changing them to promote more sex.
I know that most educated people believe that, but I've never seen a good argument for it.
At any rate I am almost sure that there are microbes causing significant amounts of death and disability (especially disability because it is a lot easier for our civilization to ignore or deny a cause of disability than to ignore a cause of deaths) that almost no one recognizes as pathogenic. And I tend to believe that for some significant fraction of these "insufficiently recognized" pathogens the more sexual partners you have, and the more likely you'll get it. (There are dozens of viral and bacterial infections -- including near a dozen at least in the herpes family -- that remain in the body and are more common in more promiscuous populations.)
In other words, there seems to be a strong selection bias whereby people tend to look only at the pathogens that are recognized as pathogens by, e.g., doctors.
It might be however that these biological dangers from less-recognized sexually-transmitted pathogens are concentrated in people who are old or already sick.
Any professional biologists or medical researchers wish to chime in?
I'm not a medical professional either, but...
Except in the specific cases of microbes that target the immune response, wouldn't you expect to see things like an elevated white blood cell count in patients suffering from a pathogen, even if the specific pathogen was not well recognized or understood? In other words, you would see the symptom in a blood test even if you didn't know exactly how to look for the pathogen.
If the pathogen reproduces slowly (the pathogen that causes TB might be one such) or has some way of hiding from the immune system or is one of those viruses (e.g., the herpes family) that get into cells and tend to remain dormant for long intervals, then they can be very hard to detect and will certainly not show up in a WBC. I saw news reports earlier this year about evidence that some cases of obesity are caused by gut microbes not previously regarded by, e.g., doctors and society as being pathogenic.
