TW Is this sexual assault?

My husband came inside me today after specifically telling him not to, I literally told him 3 times to not do it. I even pointed at where I’d want him to cum on my stomach (I don’t like it in my belly button it irritates my piercing 😩), but he STILL did, and he literally laughs at how pissed off I am for 2+ hours and won’t stop smiling.

Last week I said he could cum in me but only that time (idk if that’s relevant but I want it to be known since idk if I’m over reacting)

Can someone like talk to me about it? Idk what the fuck to do honestly, I feel disgusting and worthless like he doesn’t respect me and just uses me as a cum dump, I literally keep trying not to cry. (Last week when we had sex he also pulled out and still came inside me for half the time of the orgasim too).

Before I get bullshit comments saying “oh it’s in a mans nature, or maybe he couldn’t pull out” HE was ontop, he’s pulled out plenty of other times. AND he’s laughing at it so he literally did it knowingly.

I included the stay with him/leave him thing since I genuinely don’t think I want to he with him anymore because of it. What would you do in this situation? Is it sexual assault? Sorry for the long ass paragraph, I just wanna stage everything so opinions aren’t biased 😞
