You want the truth, he whole truth and nothing but the truth?!
Fine.
Years ago, my husband told me he likes the smell of his farts (which are rank btw) and I said it was disgusting to which he replied that's it's not, it's just honest, everyone likes the smell of their own farts.
And you know what? I've never admitted it to another living breathing soul but he's absolutely right. I love the smell of my own farts and I love farting. The longer the better, the louder the better, the smellier the better. It's incredibly satisfying.
And what's more, when I sit down to a curry or a big Christmas dinner with a nice solid helping of sprouts, my main thoughts are the delicious food and the creativity and how grateful I am for a wonderful meal but at the back of my mind there's a little voice saying "the farts from this are going to be great, I'll look forward to them".
Never admitted it out loud. Never will. Never fart in front of people. And it's definitely not some weird fetish. But I do enjoy it and I truly believe so do most people in their own little way.
Your husband is a massive liar.
