Is it normal to have nymphomania? does it even exist?

Do you think Nymphomania exists?
And if so, is it normal?

Maybe mine is more in the mind, despite having sexual encounters (not many different partners actually) for fear of some thing or another. But it's still very much part of my life, as well as in my mind.

I used to think it probably didn't exist, and the people who claimed to have it were either "whores" (either sex) trying to justify it with a "handicap", a scapegoat and justification to their sin, obviously by now you can tell I grew up in a religious household, I'm Agnostic now, but that's neither here or there.

Then after some miniscule mind opening, I was open to it, but it was probably more of a nurture type thing, rather than nature, despite being well aware of how humans interacted and were basically just horndogs who like to have a war to keep things interesting and in the toilet every decade or so (spoiler alert: I'm American)
But figured it was probably something that caused a "charge" in adolescence that was just too soon, premature, etc like molestation or elementary school peer pressure (I've heard stories, yet was not something I dealt with personally) and so that was what I decided was the common denominator. Environment.

But then looking back on things I noticed there were a lot of similarities to even my upbringing to these people I felt sorry for, or thought they were just trying to look better after doing horrible things, and it made me feel guilty.

I still don't know the right answers, if there are any, but it wouldn't be normal would it?
Or maybe it's normal, and what's preferred was normal is also a lie.
