Sex - help

My husband and I have been struggling in this area. Me more than him.

The first year of our marriage we would have sex 2-3 times a week

Once I became pregnant sex was almost like a choir for him. He refused to have sex unless he could watch porn, which really hurt making me feel like I wasn’t good enough. (We’ve talked about this since and he understands the position he put me in) My last two months of my pregnancy he wouldn’t have sex at all and only masterbate.

Now, a year after giving birth he still never wants to have sex. I am always the only having to initiate and get things started. He always has me be on top and puts almost no effort in. We have sex maybe once every 10 days (on a good week). He makes me feel almost guilty for asking to have sex. I get that he works hard and is busy from work but is it so bad to want to have sex with him.

Anyway, any advice on what to do? I’ve tried talking to him and he listens but doesn’t change. I don’t know what to do anymore
