Doesn't surprise me one bit.
I was with a man a few years ago, this guy was built kinda like Jay, took real good care of his body, worked hard at the gym, ate only healthy foods, paid real big attention in the shower, used all the expensive exfoliating scrubs, moisturised afterwards etc. This guy was immaculate. Or so I thought.
Whilst we were away on a break - bathroom door was slightly ajar. In he goes, pees and poos, flushes, then comes back out.
I said to him, "You've not washed your hands......" he looked at me as though I'd lost the plot.
When I repeated what I'd said, he replied "so.... I never do, what's the big deal, you're making out as though I'm disgusting or something - it's only my hands ".
Suffice to say: I'd heard (and seen) enough - and left him and his manky habits to himself.
