I agree with pretty much all the comments here and think you're looking for a partner with rather narrow blinkers on and agree each time you add comments my heart sinks a little more.

I'm really don't like the phrases you've used on several occasions, "convert" and "persuade". Is that really what you want to do? Sounds a bit clinical to me.

Maybe try to find somebody you like, want to spend time with and possibly spend a lot more time with. If you find a really close and loving partner and are that good together I'm pretty sure she will be a lot more open minded and receptive about WAM or anything else as she will love you for you! When you get to that place and as long as you talk everything through you will be surprised at how many women will entertain your fetish.

This is common sense.

For me in the long run, I don't someone around so I can smash pies in her face - I want someone for who they are BUT pies are a bonus. It's a thing almost of "I want to throw a pie in your face, but with love."

Perhaps this is the notion being pushed in the quoted comment.

Ichris001, You seem to be incredulous that finding a partner can't be reduced to a science or a logical process based on a roster of technical specs and user requirements - like selecting a car, a mortgage or a laptop. If I were being facetious, I might well suggest there ought to be a 'Which? Partner' publication for this - if it were possible - where consumers of monogamy could find and select their partners comprehensive listings of specifications and via unbiased, independent critical reviews (plus 'used' section)

Unfortunately, it can't be boiled down in this way because the whole is greater or different than the sum of the parts. What if they fulfilled all your criteria and you still just didn't like them?

The best way is really to live your life as yourself, doing the things you manifestly want to - giving off clear messages about your interests. That way, when you take your 'random walk' out there those you meet will at least know what YOU'RE about.

Of course they are. Like the dieting industry they rely on abject failure, guilt and deferred responsibility - but for it to look like it's working for everyone else.

Coming back to the original question, you may be starting out with a false assumption: I'm not sure that there is such a thing as "the vanilla pool". It would be more accurate to compare Fetlife etc. with the general population, i.e. if you meet someone outside the kink community then you don't know whether they'd be interested in WAM (or any other fetish).

I read a Vice article a while back:

One line in particular stuck in my mind:
In the catalogue of possible sentence-enders to "we need to talk about my out-there fetish", "I want to throw custard at you" rates somewhere between "no big deal" and "OH THANK GOD", depending on how vivid your imagination is.

I went along to the London Splosh Games again today, and I met a few women who started out by saying "I've never done this before, I'm a bit nervous" and later said "That was so much fun, I definitely want to do it again!" Granted, I've also met people elsewhere who tried getting a pie in the face and said "Nope, not for me". So, I'm not saying that everyone has an "inner WAMmer", but it might be more common than you think.

This may also depend on how specific your preferences are. For instance, do you need your partner to wear a wristwatch, white socks, and have a scrunchie in her hair? Or do you have strong feelings about the relative merits of shaving foam pies vs. whipped cream pies? I think that the more flexible you can be, the easier it will be to find a compatible partner. However, I realise that you can't pick and choose what your fetish is.
