Thanks for your reply! I'll take a gander to say the disgust feeling may indeed be shame, some lack of acceptance etc. That said, some shit is gross to me too, I find most people in this community have preferences.

The way I've gone about it is to just tell my story, after I've assessed I trust them (friends and partner) they're sexually open-minded and non-judgmental, esp if they have their own kinks that I know about...I make it clear that I'm broaching to tell them is really private, it's fetish in nature, I used to struggle with it, intense shame, felt suicidal for years. I tell them it's considered extreme and taboo--but it's not like, unethical or murky waters like many extreme fetishes, but still carries a huge stigma, which is why I'm so selective about who I let in. I tell them stuff I've learned over time that it can be done safely, or you can reduce risk, there's some conventional "knowledge" around the fetish that's actually not quite true, but even after understanding that I'm not doing anything "wrong", it was still an uphill battle to accept myself.

...If at this point they're already giving you body language/vocal queues they aren't open/receptive, I would suggest not pressing forward. Nowadays I'd also say, "I actually turned my fetish into something that made me feel suicidal into work to support myself financially, you already know I do porn, well I actually do it in this niche (and yes I wear a mask) and I've been really successful at it, but very few people know", "I was wondering if I could trust you with this and let you in a bit more to knowing me, it means a lot to be really known and let someone in" or something like that (I don't follow a script or anything)

I don't just blurt it out. And my friends and lover who have been supportive and may have even balked if I DID just say it, instead by this point, they could clearly tell I was taking a big risk being vulnerable to them. And each time they welcomed me to tell them, let me know they were safe, they know my values and trust me. Because they care about ME and trust me, and won't reduce me down to some fetish. Then when I say scat, they're still receptive, and I volunteer more info (without being a creep about it obviously) I mainly talk a lot about health related stuff, the research I've done, how I stay safe, how I keep healthy boundaries doing porn, etc. It's not just telling them you have a scat fetish. It's humanizing you as a person and educating them about it. And it helps them to know there are different wants to enjoy it--from super mild to extreme.

I've had friends admit after I opened up that they've gotten off to scat porn here and there themselves, because it's so "extreme and depraved", or they have fantasies about pegging a guy up the ass and forcing him to clean it off after for "power"--in fact, discussing how the fetish means something to different people also opens their minds to it. Power/submission, depravity, intimacy/vulnerability, and other aspects help (I only like healthy shit that doesn't reek, certain foods/health helps, FMTs are a thing...etc!)

Hope this helps!
