Am I the asshole for not jerking off my husband for iui

My husband is mad at me for not “helping” him produce the sample for our iui. I’m like gtf over it. I’ve had countless vagina ultrasounds, had a dnc, have had 2 iui procedures and months of negative hpts and he never even bothers to ask hey are you pregnant this month? So I feel like if this is the hardest part of our pregnancy journey for him he can stfu! Like, sorry you have to watch porn and jerk it into a cup, now let me just go to the clinic after this and have a nurse jam something through my cervix and hope it impregnates me. Am I being a bitch here or is he over reacting?!?
