I don't think durian smells that bad anymore, and I never associated the scent/odor with anything, either. I remember when I was young, I was watching a documentary on durians and a woman said it smells like a toilet. I laughed. Anyway, I think durian tastes like some sort of ice cream which is good, but I'm not obsessed like my mother.
Mangosteen... I've never heard of it until now.
