Sex is fun. That's why we do it. Sure, there's that pesky animalistic thing about procreating, too...but mostly we do it because it's fun. When reference is made to sex being fun or pleasurable people usually associate it with climax- cumming, orgasm, et cetera-and for some this is, in fact, the "fun" of sex. Climax is the goal, the aim.
"nymphomania- (n) abnormally excessive and uncontrollable sexual desire [in women]"
"Satyriasis" is the given title to a "hypersexual" male.
Hypersexuality is an actual affliction. As is outlined pretty immediately in the link it is thought to be caused by a physical dissatisfaction with the sexual experience calling for constant genital stimulation without satisfaction (often even after climax). Though this is an acceptable theory, it also known that this is NOT the only theory and, according to many afflicted by hypersexuality, not the only cause.
I, personally, agree this may be a cause, but I also believe that more often than not it is rather a symptom. Here is my evidence for this:
Nymphomania, satyriasis, hypersexuality-whatever it is called- is often recognized not only by the all-consuming need for sexual stimulation or ever-present sexual thoughts and tendencies, but also by the afflicted persons taking drastic and often dangerous measures to achieve sexual stimulation. Promiscuity manifested in acts such as sex with strangers, sex in public places, unprotected sex, et cetera is characteristic of someone with what I will from here on out refer to as a sexual addiction.
I do not dismiss that sex addicts, like all addicts, take drastic measures to get their "fix" which would corroborate the theory put forth in that article and I will again say that I do not completely denounce this theory. I believe that the people for whom the former theory is true are still capable of emotional attachment and thusly may have a neurological affliction as their primary deficit. I believe the people for whom my theory is true have a mental or psychological deficit which actually impedes their ability to achieve sexual gratification though they constantly feel the compulsive (and frequently obsessive which is why I think OCD is also possibly linked to this affliction in certain cases) need to engage in sexual activities which are often not pleasurable at all but painful and demeaning.
People for whom the latter theory is true do not merely seek a more powerful climax but seek something else. Somebody who only searches for a perfect orgasm may be content with doing that with a single sexual partner or at least in a "safely" (relatively speaking) promiscuous manner. The sex addict to whom I refer engages in sexual activities without emotion or conscience. Though they may later consider their actions regrettable, it is usually after unpleasant ramifications (loss of friends, unwanted/unplanned pregnancy, or transmission of STDs). Point being that conscience plays a minute role in this disorder. These sex addicts do not care who they are "cheating on", cheating with, that they are who somebody is being cheated on with, whether they are passing on sexually transmitted diseases, and the like until it actually happens and they are personally affected by it and even then the reaction is so much lesser than that of a normal person.
For this affliction, for this addiction, treatment is absolutely necessary. Though it may take a while to recognize and even longer for the addict to admit to their problem (if they ever do), it is imperative that they receive help before it ruins their life. Chances are their satisfaction can be found in a way completely unassociated with sex and, after the reception of this, the addict will possibly be able to receive complete gratification from sex and orgasm
