You know what, just because you fart does not correlate that your shits will smell or the farts will smell.

An example is if I eat a huge veggie meal close before bedtime, when I get up I will have a few huge farts, the really loud and hilarious ones!!! But there is absolutely NO smell they smell like air, like nothing....what a funny way to start your day.
But some of the smaller less loud farts are lethal, like the ones I had from having the cheese sandwich, yikes.
I also enjoy sneezing too sometimes. When I sneeze its a loud screaming one, the one that scared people, yes I do it because its fun and it feels good. Something about the release of foreign air and particles I guess. But yeah if it smells it is kind of embarrassing.
....So only consistent smell would be concerning to me, unless I shared a small apartment with all girls or something.
I have a girlfriend who has NO sense of smell, really, she cannot smell anything hardly, from birth. This is one reason why she makes a good friend, and I think lots of guys like her for that reason too. I have a hyper sense of smell unfortunately, to the point that I can small my mom boiling WATER downstairs, freaky.
