To not want sex and be allowed to say so

[Carpetness]

So my mum died last week. Had a long drawn out battle with a brain tumor so it's been understandably shit.
Haven't been intimate with my partner for ages. Last night he tried to initiate it and I said I didn't want to. Said I'd just lost my mum so was preoccupied. Then this morning tried to initiate it again. Again said no.
His response " do you want to have sex ever again?!"
His sex drive is high (always has been and mine never has). He just keeps saying " I need to ejaculate". What the hell!! I feel bad that I never want it but am I being unreasonable to want it even less when he's going on like this. I think I feel bad as I never have initiated it really so he probably feels rejected. And when he feels sad having sex makes him feel better but I'm the opposite.
Just need to put this somewhere

Ugh, he sounds vile and revolting, tell him to ejaculate in the fucking toilet

You are not a vessel for him to ejaculate into. What a horrible and deeply unsexy way for him to put it, which makes it all seem to be about him needing to scratch an itch and sodding whether there’s any pleasure in it for you.

He just keeps saying " I need to ejaculate".
Disrespectful and selfish given the circumstances

Jesus christ. Him saying he needed to ejaculate would make my vomit un my mouth. I used to be with someone like this and i left him. He would pester me for sex like this all the time. Fuck that! Its not normal.

The answer to him needing to ejaculate is in his own hand, literally.
Not exactly get you in the mood speak, is it?

Vile.

I cant beleive some of you are saying saying that his need to intimacy is stringer than ops. Intimate is not the correct word for this. It just sounds like the husabnd needs a hole to stick his dick into. Hardly intimate when hes pestering the OP.

I had one of these. Said he ended up depressed if he didn't have sex. Used to beat me up too. After 7 years I shut the door on him for the final time.
