in any sense it does release chemicals from the brain similiar to drugs creating or releasing or hmm, what do they do, i mean we got seratonin, dopeamines and then endorphines with sex.
Along those chemical lines, that is why i'd say sex is a drug.
Then we have addiction potention. like any other drug
sex can become addicting, it can be abused, and you can become a frequent user, you can get withdrawls from it. People need their sex. You may have to slowly ease out of it when frequent use is gone, by resorting to masterbation, but its not quite the same.
