Ok, so I apologize for the TMI, but I have ALWAYS been a super smelly farter. It runs in my family. My mum has the stinkiest farts ever and so do me and my sister. I know it isn't an intolerance, and I do all the things that have been suggested to minimize it, but it's just the way I'm made.
When I was younger I was embarrassed by it, but then I decided that if I can't help it then I shouldn't be ashamed. So now I take pride in the fact that I can stink DH out of a room even though he's a big burly bloke and I'm little petite me. Even when he loads up on Guinness and pub food he can't compete with my stink. The best part is that mine are almost always silent so I will slip them out without him noticing and then laugh like crazy when it hits him.
So, I have to ask, is anyone else like this??
