My question is about watching porn

I would take this more seriously if you didn't have to hide behind anon to say it.

You're idiosyncratic if you think I have to hide behind anon. Very foolish

I am idiosyncratic, to be fair.

He might have felt like it'd be rude to wake you. As much as I like sex as a guy, if a girl woke me up for it I'd be fuming. Man needs his sleep. Suppose he thinks sleep is just as important and therefore assumed you wouldn't want to be woken. If you tell him that if he feels horny in the night and wants sex then it's okay to wake you (assuming it is actually okay, I get that impression from your post - if not then you should be able to understand why he didn't wake you lol).
As for him watching porn generally when sex with you isn't on the cards, it's perfectly normal, you can't always have sex when you want to which is why people masturbate. It's also perfectly normal to have celebrity crushes.

Also to those saying porn is unhealthy, it's not inherently unhealthy - obviously if it's causing negative impacts on your life then it's a problem, for example in OP's case if it meant you were having less sex because he was favouring masturbation then something may be up. Generally, though, it can be consumed healthily. Saying it's potentially harmful and addictive and therefore you should never consume it is nonsense. Many things in life are potentially addictive, doesn't mean everyone's going to suffer from an addiction with them. Most of us have adequate self control to have these things complement our lives rather than negatively impact them.

Pornography is a drug - and it's free and easily accessible. Talk to him about how it makes you feel, and tell him it's you or porn.
