Crotch smell

You know that odour that starts coming from your crotch after ~4-5 days of not showering? It smells like a mix of sweat, semen and saliva. The thing is, I really love this smell. It's almost intoxicating. I've found that at day 7 or 8 the smell has matured to its peak and you can just spread your legs and take a nice whiff and feel the goodness.

What I'm wondering is if there is a scientific explanation for my love of this smell.

It doesn't really have anything to do with where I live. I just happen to stay home for weeks at a time and sometimes I don't bother to shower. If you still want to know, I live in Sweden

I'll try that as soon as I get one

You'd have to get me drunk first

I considered that but I think it's only a minor part of it
