Until recently he has done a manual job which left him filthy.
He would shower and shave as soon as he got home from work and go to work in the morning, as he fell out of bed (did brush his teeth)
At weekends he would have 1 shower and 1 shave a day. i.e if he was going to be gardening later, "there's no point showering in the morning" regardless of what might have gone on during the night , or how warm it was etc.
I always, without fail shower when I get up. If I need another one later, I have it.
I work (in an office) with a load of lovely, sweet smelling, perfumed men and I do find myself wishing that he'd make the same effort.
He now works in a office, but has stuck to the same routine and always comes home stinking, which must be horrid for those he works with. It's weekends that bother me TBH, because he's just not nice to kiss/cuddle unless it's within an hour or so of his evening shower.
He also refuses to shave more than once a day. I know some men don't need to, but he does and because he shaves in the early evening, he spend most of the day looking (and feeling) decidedly unshaven.
