Hi there Tracy.
I read your history & clinical descriptions with interest but there are a couple of lacunae that need filling in.
Are you married, single/multiple partners? Is this problem with the same partner or with multole partners?
It may just be that there is a psychological element to the whole scenario & the smell may be more 'imagined' than real. Does you partner/partners feel the same?
I would advice meeting up with a venereologist on the ground & running a few tests & making sure that all is well in person.
Good Luck & do practice 'safe sex' in the interim!
