God Made Nymphos Too?

Going by a thread that has been going on for a couple of days now-"Will you forgive a cheating spouse?"I started wondering,what will actually make a person cheat?What goes on in the brain of a cheating spouse?What happens if a woman/man is never satisfied by their partner,should they just die in silence?
What of nymphos?Was it God that made that that way?Whats the justification for wanting too much sex?How can nymphomaniac tendencies be controlled?
Opinions please.

Whether the condition of insatiable sexual desire is exhibited by females (nymphomania) or males (satyriasis), it is still something that must be addressed.  Any appetite manifesting itself to excess must be controlled. 

Consider this--If you ate nothing but a particular food and you ate it until you became so full that you regurgitated, then that's an obsessive behaviour.  Not only has your extreme appetite made you ill, but by not eating other foods, you have also compromised your health even more.

The same with any behaviour.  If a person is compelled to cheat,  then that person is denying him/herself the stability of a good relationship and violating the trust that others have in them not to stray.
