Everyone has a distinct smell so when two people move in together, which smell remains? Does one person adopt the other persons smell or do they develop their own mixed smell? Also when they break up who keeps the smell? Or do they both go back to their old smell or get joint custody of the smell?

You mean like, smell of deodorant or colognes?

Or we talking about the smell of ass & ball sweat, cos bruh, shower.

I guess it has to mix, naturally we both smell about the same. After a shower there’s obviously a distinct difference though

What…? Wouldnt… wouldnt it just work the same way as putting any two other smelly things in the same room? Like, if you put a fresh baked apple pie and a chocolate cake in the same room, you would smell both, and when you removed one you’d pretty quickly stop smelling it, though it could linger a bit and the more the deserts have rubbed off on each other, the longer the smell will linger

My favourite perfumes is a mix of two. Odours mix all the time and create new odours.

Couples who are attracted to each other , have dissimilar immune system genes ( known as MHC) . It helps their subsequent kids have stronger immune system .
