Wow, that's a pretty.. Um.. Direct question...
Unfortunately, Blurtit is more of a Q&A community where people try to help others out with specific questions or problems they're facing.
It's not really a private chat service or a niche dating site, there are other websites that do that much better than us.
If you're asking where you might find girls with body odour, I guess you could try going anywhere that people are likely to sweat... Like a boxing gym or something maybe?
Or are you looking for women that have a particular type of body odour? I had a quick look on Google, and there don't seem to be too many groups or communities based around this particular fetish, so I can see why you might be having a hard time.
There are a couple of blogs on the subject that might be worth following, although most of them seemed to be based around "armpit fetishes", and I'm not sure that's exactly what you're after.
