Bit of back ground, I have sleep apnoea and use a CPAP machine
So last night as usual I took myself off to bed and left OH playing on his PS4, this happens most nights as he can't sleep before 1am and I like to go to bed around 11. Anyway at midnight he comes upstairs, has a shower, watches a bit of YouTube then will get in bed around 1.
I don't have an issue with his routine he can do what he likes, he's a 40 year old man. My issue is he will turn the big bedroom light on (his bedside lamp is no further then the light switch) which will 9/10 wake me as it's bright then will potter around the room/play a game on his phone while his shower "gets warm" then after his shower he will sit on the end of the bed, wake me to move my feet!! as they are in his way for sitting at the end of the bed while he air dries!! he will sit there watching his videos (with headphones but it's still load enough I can hear) then at 1am he switches everything off and goes to sleeps. Now I'm wide awake!! 
We also have a DC(2) who sometimes wakes in the night as well
AIBU to ask him to do his little shower routine before I go to bed so he doesn't wake me up?
I mentioned the CPAP(which I have a love/hate relationship with) as sometimes I fall asleep watching TV so don't have my mask on so he will wake me to tell me to put it on, but he will wake me as soon as he comes in the room to put it on then sometimes I can drop back off while he's in the shower but then am woken AGAIN while he dries off.
