I get a ton of passing nasty comments on campus but never from my family.
I have a twin and she says she does not smell anything whenever I visit her and she has small quarters. She eats horribly and does not even have this problem. If anything her system works like way faster than mine. I think my grandfather may smell something though and is being polite. I sit in the car with my mother sometimes and even go shopping with her occasionally when we meet up and she doesn't seem to notice anything.
I heard from someone on this forum a while ago that if you lick the palm of your hands and smell it then you probably smell like that. But I don't think that that is very helpful.
