What causes sexual addiction?

Answer 1

If you are referring to the real addiction that goes above normal range and starts to become a psychological problem, then it's called "hypersexuality".

It's really debatable whether it's a real "addiction" or "mental condition" at all as far as that goes, however.

Some treat it like a normal addiction (such as a drug one), while some think it's a form of sexual compulsivity (associated with obsessive compulsive disorder in a sense) and impulsivity.

Others say it's a myth made up by today's culture/society.

In my opinion, an addiction is any activity which you do on a considerably higher level than others, which you can't cease even when others are bother by it and even when it does damage to any area of your life, when it alters your behavior in any way and when you tend to prioritize it above every other thing present in your life.

I also recall "nymphomania" being the term referred to hypersexual women exclusively and I briefly recall something about "premature ejaculation" as a male reference to it.

Answer 2

There is no formal definition, however this is a good working idea: an addiction is something that consistently causes problems, but you go on doing it anyway even though you know you should stop. See if that fits.

Answer 3

It is not clear that sexual addiction really exists.
