Sex after birth

So I just had a baby not long ago and my fiancé and I can finally have sex again and I’ve missed it sooo much since I absolutely hated it while pregnant. Well before I was pregnant and in the beginning of my pregnancy I had no problems getting off at all. He could get me off multiple times but now it’s like no matter how much we have sex I can’t get off. I don’t think it’s him...I think it’s my body out of whack. I’m super frustrated about it and I’m afraid he thinks it’s him. I feel like a broken toy. It doesn’t help that we can barely have sex bc of the two kids. I miss being close with him and I miss getting off I’m super irritated about it! I’ve thought about getting a toy to help but my fiancé is old fashioned and is iffy about it. He thinks if I get one it’s bc he isn’t doing it right 🙄 has anyone else had this happen after a baby?
