First of all I think the threshold on that definition is too low. That's only once a day or a couple times in a day and skip another day. While that's a lot of sex, it's not "hyper" anything.
The next thing is that it says desire. A person could have high desire and no sex. A person could have (bad) sex with low or no desire. Calling once a day sex hypersexual desire is flawed. Especially among young males!
i'm a young male and i want sex all the time. doesn't mean i am gunna get it but i still want it.
