TBH it sounds as if he has some issues. Not exactly 'controlling' but along the lines of OCD. Not allowing you to sit on his sofa etc.
That is not normal behaviour.
On the other hand, disregarding him, I find it off that you don't feel you need to wash before going to bed.
I'm always shocked at the personal hygiene posts on MN as so many people only shower now and then.
At the end of the day, after you've poo-d, you at least need to wash your bum, and even if you think you don't smell, you will have sweated all day.
And if there was any chance of sex, then you bits need washing.
(And yes, we all know you can use a jug of water, a flannel, a loofah and god knows what else - but just jump in the blinking shower for 5 mins!)
