Well I think I may have a problem. Im not trolling btw. When Im around my friends and someone lays a fart I will just stand there and absorb all the gases in while acting like I don't smell anything. Also sometimes at the store I may cross someone who happened to lay a gas and try to get as much of it in through my nostrils. Every fart smells different and I have yet to smell one that smells the same. I also love the smell of my own farts. Is this normal in any way?
