No one I've ever known in reality is into getting messy or muddy, which makes me assume these fetishes are somehow fake. I've talking to hundreds of people who have never heard of this or think it's childish and crazy.

So my question.. how do i meet real girls who are ACTUALLY into this fetish, not just a model getting paid, or a bot pretending to be real.

Women with these fetishes do exist but it does seem to be pretty rare. Some of the mud locations I use were shown to me by a couple who are both into mud. However they are now broken up. Having the same fetish doesn't mean you will be compatible or even like the person.

My best suggestion would be to use fetlife and find a local munch and meet some people in person. It's not likely you will find a woman with the same fetish but you might find someone open minded enough to try it.

Actually, the odds are far better than you might think if you dial down your expectations from finding a female mud fetishist to finding a female who would be receptive to slippery good fun in pottery clay with the right guy. Keep in mind a female will generally have no interest in being the object of fetish desire, rather, she will be looking for someone who values her as a person, not as a sex object, therefore, whether she would be interested in your attentions really all depends on you and what you are looking for. She can tell the difference incidentally...

There are psychological studies that suggest nearly half of all females have some level of interest in a sex fantasy involving a slippery substance. Obviously, nowhere near that number will ever try to make that fantasy happen. The thing a mud fetishist needs to keep in mind is that it is up to him to make mud fun and the woman interested in having fun with him in the mud. If you concentrate on meeting new females, the odds are you will eventually find the one you are looking for...

So stay away from natural mud scenarios unless you have a pottery clay equivalent mudpit and fairly private access. Learn to handle the logistics of doing pottery clay in some sort of inflatable pool or similar. And learn most of all to be cool about whether it happens or not, again, females are turned off by fetishists that treat them as objects...

Just adding to what @Quarryman said; You have to meet people on a personal level, find a someone with whom you have a good rapport, then, after you've established that you're really into each other, you can begin exploring some kinky ideas.

The first gal I ever had sex with asked me to stop the car one day, as we were driving past a muddy field, so we could get out and have a mud fight! I wish I hadn't been so young and self conscious. We both got covered in mud, but we were in plain sight of the road, so I was rather nervous. She, on the other hand, walked up to the edge of the road and waved at passing cars. I would not join her.

Several other women I've been in relationships with have enjoyed some messy play, or joined me on my swamp adventures. I also had a model ask me if I knew of a place where she could get muddy. She was a natural in the mud, and it wasn't for the money, or even because I suggested it.

You're just not going to find many people who are hanging out in bars or on-line with a sign that says "WAM me". The real problem goes back to what @Quarryman said; women don't want to be an object of your fetish. If they advertise an interest in a fetish, they are mobbed by fetishists who don't even see them as a person.

I totally agree. It's nearly impossible to find a partner with exactly the same fetishes. However, if you find someone who is open for new things and loves you for who you are, you can get lucky. WAM is also fun for people without an explicit fetish for it, so don't limit yourself too much in looking for the ideal person
