defined "a woman who has abnormally excessive and uncontrollable sexual desire."  

and from the few times I interacted with her, I'd say she was very accurate in describing herself that way.

I imagine that it could lead to problems if the woman really couldn't control it.
When I was a freshman in college there was a beautiful blond who was rumored to be a nympho but alas, I found that it wasn't true

Have not had the pleasure of meeting her.

I saw a lady in NJ a few years back that told me she had 11 appointments in a 14 hour workday.  From what I know, she didn't need the money.  I've known several who have scheduled appointment far in excess of their financial needs.  I'm not a shrink, but I think I've encountered providers who are at least borderline nymphomaniacs.

my opinion changed drastically.

I've known two ladies who were flat out nymphomaniacs. Having sex with them was a near death experience. One of the great things about this hobby is the nuance that's involved in a session. When you're having a session with a nymphomaniac, nuance is thrown out the window. When you're done, get the hell out, and bring on the next guy. If you're into hard charging, and nothing but sex, they're available. I prefer subtlety.  

I don't think I've encountered any women who are nymphos by the classic definition quoted above.  they were not out of control.  But like you I've met several who were serious, multi orgasmic and enthusiastic, and really loved having lots of sex with lots of guys.  One lady I met this past year happily proclaims herself to be a slut and we had fun exploring our slutty natures together.

Searching for those ladies who really into more than one male might be a clue. I think I should avoid them because I am a one and done guy LOL. They would probably put me out of commission for weeks.

Here's a chick that openly advertises being a nympho.

describes me also!  I've had to learn how to really pace myself so I can take full advantage of a lady's company!  I'm thinking about a double date as a birthday present to myself but honestly don't know how I can deal with two women. Might be fun trying though!

go for it. There is a lot more than 1 orgasm to enjoy. Make sure the 2 ladies know and enjoy each other.

Yes, go for it. Having two fun ladies playing with me and each other is such a wonderful tactile and visual experience. Specially when the ladies like each other. It can be intense or can be just fun and laughter together. The best has been when an ATF suggests someone to join us because the ladies have been all in and i have the comfort and trust with my regular lady.

But uncontrollable? Nope, I am in control and always exploring!  My appetite is just very strong...my tastes for variety and spice as well!  Have a caliente 2016 planned!  Catch me if you can in Crystal City 1/13-1/19 after a vaca hiatus!

I like A LOT of variety however.. in my partners and in the situations I play in. Variety is what keeps me wanting more and more after all these years.  Sometimes I want to make love, sometimes I want it down and dirty, sometimes I want kink, sometimes I want to be pampered, sometimes I want dinner and romance, sometimes I want orgies etc etc.

I love crazy sex sometimes, but certainly not every time.  I also enjoy making one beautiful romantic moment with one person last and last and then cuddling up in bliss after.  Nympho to me means I want it ALL!

It's definitely no secret that I'm a total slut and nympho!  Bring on the cock!  Lol  
XOXO,
