I have seen sexual addiction from the outside, loving someone who struggles with this problem and I have to agree with Chacha it's more about self esteem issues than any chemical high. The chemical high makes the self esteem issues easier to ignore much like alcohol can for some addicts.
I think that an addiction to sex is not about addiction really. Sex is not an addictive substance like nicotine. It can chemically force you to seek after it. But here is the thing, if you have that sense that you are "not okay" and that doing X will make you "okay" (i.e. feel wanted, desired, loved). It is more about obsessively filling that hole in your life than it is about exactly what you are addicted to. It's not about the sex, its about fulfillment and people having a skewed sense of reality that sex is their only way to fulfillment.
