Do you think there is abnormal consensual sexual behavior? If so, do you believe it can and/or should be treated?

This Congress dude is supposedly getting some kind of treatment for his internet affairs. Like, are affairs abnormal? Are they something that can be treated? Is it different because he took pictures of himself? Is that abnormal?

There is a controversy about so-called sex addiction, too. The psychiatric community does not have a consensus about its existence, but people are making a lot of money treating it.

Mostly it seems to mean spending too much time having sex or pursuing sex. It can mean picking up a lot of people for one night stands. It can be having several affairs at one time over a period of years. It can be masturbating all day for many days to internet porn. It can mean a pattern of relationships where one lets oneself be manipulated in return for love. How is this different from codependency?

I’m talking only about consensual sexual activity between adults here. No rape. Nothing with kids.

How much sex is too much? How many partners are too many? How much time spent masturbating is too much time? Where do you draw the line? Is it different for a married person than a single person?

Is it a psychological problem? If so, can it be treated? Should it be treated? How would you treat it?
