Stop being a pussy, tell your partners about your fetish.
I’ve seen too many posts about people whining that they’re afraid of telling their partners about their fetish and I’ve had enough.
Just do it. Tell them. If you trust someone enough to let them see you naked, touch your genitals, OR SPEND THE REST OF THEIR LIFE WITH YOU (in the case of people with wives/husbands), you should trust them enough to tell them you like smelling farts.
I’ve sniffed the farts of EVERYONE I’ve ever had sex with. Many of my female friends fart around me. It’s really not that big of a deal. Yeah, your chances of finding someone who will also have this kink from the start are slim (I move in some kinky social groups and I still haven’t met anyone who had the kink before we met), but your chances of finding someone who will be okay with it and willing to indulge you (even if it takes them a bit of time) are MUCH higher than you think.
For context: I’m a trans lesbian and that shapes my perspective on all this. I’ve had to work through SO MUCH shame that society imposed on me that I’ve sworn to myself to never let shame hold me back from enjoying life ever again. I’ve had to tell my friends and family that I’m a trans woman, something many of them have only ever seen in porn or as the butt of jokes in horrid sitcoms. And I got over the shame and did it.
If you can’t tell your PARTNER about a stupid little harmless kink, you’re a pussy. Plain and simple. Grow the fuck up.
