My former husband worked as a house painter, so physical labor. He showered twice a day...once in the morning before work, and then after he came home from work. (His choice) If I happened to catch him right after work, before his second shower, no problem because on him "clean" sweat smelled waaaaaaay different than sweat and greasy hair that's been accumulating on someone over a few days. I found his "clean sweat" to be rather a turn-on!
Stinky......smelly......accumulated sweat....total deal-breaker!
