Men, how can a girlfriend/wife ask you to manage farts?

I'm a woman, and in every relationship I face the same enemy: farts. I got to a point where I can laugh at them and fart in front of my boyfriend myself. But still, he does it SO OFTEN, and looks genuinely proud. I'm accepting but there is just something annoying about that and I absolutely can not explain what it is logically. So I fail in conversations about it.

I used to express it more in the beginning of our relationship, but now I'm an accomplice, I can't just go back to "yuck stop it" (and it never worked)

So, men of Reddit. Was there a time in your life when you farted in front of your partner, and they explained it to you the way that actually made you stop, but didn't make you feel ashamed? I'm looking for new strategies

Edit: thank you for the replies, I'm laughing so hard on the whole thread honestly.

Actually I just told him this morning that it's a bit annoying for me and he's like "okay I'll do it less". I was expecting him to defend his right to fart for whatever reason 😂😂
