What would u do..?

I’m 6 months PP . Had 2 kids back to back. And my husband & I are constantly arguing . I’m a SAHM . I cook, clean etc. I’m just tired and my husband complains bc I don’t give him sex. My sex drive is so low right now. I have the IUD which feels so uncomfortable w/ certain positions and this morning he got butthurt bc I didn’t wanna fu##! Basically wants to kick me out bc of it! What do i doo... am i in the wrong for this ..

Sometimes i feel pressured into having sex w/ him and i tell him when we have sex I’m not gonna be into it bc he’s always nagging .. he doesn’t care. he always wants it and it’s starting to aggravate me..
