Nymphomania is Female Specific
Although the term "nymphomaniac" is not frequently used in everyday speech, most people are familiar with it. It was the name of a movie by Lars Von Trier, and the famous line "if you be a nympho, I'll be a nympho" was in the song Candy Shop by 50 Cent. Unfortunately, Mr. Cent misused the term because he didn't take into mind that it is gender-specific.
According to the definition of nymphomania, which only refers to women, 50 Cent is not a nympho in the strictest sense. The female forest spirits known as nymphs in mythology were honored when the term, which means "nymph madness," was given its name. However, the word has a male equivalent known as satyriasis.
Like nymphs, satyrs are mythological creatures, but they are distinguished by possessing a goat's lower body. The most well-known of them, Pan, has a reputation for immoral behavior in the past. To refer to these concepts in a gender-neutral way, we might use terms like hypersexuality or sex addiction in contemporary speech.
