I've noticed that sweat doesn't smell if you sweat frequently. Whatever makes sweat smell gets diluted and flushed out. I sweat profusely on a daily basis. It cleans me from the inside out and I only need to bath about once a month now.

In the case of the female masseuse, I'd prefer she be sweaty. In the case of the overweight man, not so much, but it wouldn't be a problem unless a strong odor was present.
