Uh...no. Nymphomania is an alternate sexuality the way bulimia is an alternative approach to eating and alcoholism to drinking. It's a problem of excess and messes up your life about as much as the other two, long term.
Homosexuality could more usefully be compared to...vegetarianism, or something, but at that point I'm not sure what the point would be, and the impression would be given that bisexuality is normal and heterosexuality is like being a carnivore. Which would be an odd impression.
@Creedence Leonore Gielgud: I'm no authority on David and Jonathon, but you're wrong about "few straight men would go on record claiming to love another man, more deeply than [they] ever could a woman."
That is, it was relatively normal for a very long time to do just that. Male friends were much more important than wives; many modern romantic conventions were invented in the context of male friendship. Marriage was a matter of appetites, politics, money--your soul went into friendship.
So, it's very possible Achilles was fucking Patroclus and Antonio wanted to kiss Bassanio somewhere more personal than the lips, but it didn't look nearly as obvious or central in either of the very different earlier centuries they come from, before we came up with the very recent modern rules about male emotions.
Always surprises me how few people are aware of that.
