SO is driving me CRAZY

Hey ladies so I had my baby 2 weeks ago. Since having my baby all my partner talks about is having sex. Like it's becoming rediculous. He works from 6:30AM-4PM so when he comes home I love to spend time together. Talk about our day, watch a movie together blah blah but since having the baby all he wants to do is talk about sex. He will even message me at work and ask for nude photos of myself and that's never happened in our relationship before. I've always sent them without being asked but nothing turns me off more than being asked for them. I'm at home with a newborn and he thinks I have time to be sending nudes? And than as soon as he comes home he will talk about how he wants sex and asks if I'm better yet and if we can have sex. I got stitches internally all the way down to my anus and he keeps saying "let's just do anal" and I keep saying that I have stitches and I just don't want to! He will even call me after work and tell me the exact weeks and how many days left there is until we can have sex again! It's becoming an issue and it's getting to the point where I'm so turned off I don't want to hear another peep from his mouth.

It's never been like this before! Has anyone else had the same experience? What should I do? And what should I say to confront him about it.

I should also add we didn't have sex much through my pregnancy because I didn't want to and he was always like "that's okay baby you don't have to do anything you don't want" and that was the end of the conversation. Like wtf!
