Well, I know it seems off-topic now that the discussion has turned to vaginal odor, but yes, I competed in quite a few natural shows. From 1989-1994 I did almost a dozen shows with the ANBC and ABCC. ANBC was a natural for life organization that used to have a ton of shows in the Northeast - folded a few years back.
I have done four tested NPC shows and the most recent one was the event I won an Overall at. Clearly I am not a great bodybuilder or else it would not have taken me that many years to win a freaking show.
Again, what do you consider natural? Lifetime drug-free, 5 years, 7 years, one year? Whole other discussion.
