Men get horny when the glands that make our cum, and our balls get full regardless of anything else. It gets stale and can mineralize and you can get stones similar to kidney stones, and sperm also only have a limited shelf life, so the plumbing needs to be flushed pretty often.

For women it depends on where they are in the menstrual cycle, reaching their peek level of horny right when they are most fertile.

That's strictly biologically speaking. Psychologically speaking, there are men who never want sex or even to masturbate for whatever reason, and nymphos are a thing. Some people just don't like or want it, which is harmful to men and can give you prostate cancer, seminal vesicle stones, and all sorts of other ailments. Conversely, there are some that love sex and will act horny and have sex like thy were even when they aren't horny because sex and masturbation are fucking awesome.

Hope it helps, and you learned something.

No. Women are as horny as men. But there is an asymetry: in general, if a woman asks a man for a fuck, the man will rejoice, but if a man asks a woman for a fuck, the woman will take it as harassment. In general.
