Why isn't my vagina working?

My husband and I have been together for 20 years we are currently expecting our seventh child my last child is almost 4 months so we didn't take a break I feel so bad for my old man because before I got pregnant with my last child we had a very healthy sex life like everything toys movies creams lotions candles costumes everything you can think about we had fun when I got pregnant with my son the kitchen closed like there was no cooking in the kitchen I don't mind giving him surprises but there was no revving my engine now I just found out I'm pregnant again and he's always insinuating making comments and touching me and I feel bad because nothing works like I don't have any interest in sex anymore when we do have it it's awesome but I feel like a piece of meat because then after words his attitude changes towards me BTW he doesn't know about this new pregnancy it's a surprise for Father's Day.
