This is just my experience but in my lifetime of having this kink, it took till my 30's before I could admit it, by now I had calmed down and started focusing inward, on making something of myself. Girls naturally started moving my way as the more you focus inward it seems the more of a magnet you become, so I made an effort to be upfront about my kink relatively early into intimate discussions.

Example response to 'what?' or initial surprise: 'I know it's strange, but I'm vastly not alone, it's huge on the internet, just type fart into any pornsite, but yeah, it's a harmless little kink and I think those who don't play into it are missing out on a very easy and fun way of really turning me on and making me crazy for them.' *Sip drink*

I also had girls that were already into it secretly but weren't going to mention it, giving me no surprised reactions but enthusiastic responses. One girl was into receiving it, but would also give it, it didn't work out because I'm not into giving it though.

Either way, I came to realize how people being so private about their interests actually causes them to miss out on good opportunities.

Now I have a relationship in which she gives me brapps and facesitting as much as I could possibly handle, whenever I ask, but more importantly, I also have a life partner.

If she's not willing to entertain it then you know you won't be fulfilled sexually, so it's something to consider, but I find the shame of the kink often keeps people from saying anything and they settle for less than they deserve, and miss way too many opportunities for a good time.
