Am I over reacting?

My husband and I are trying for baby number 2. I had asked him he wanted to have sex when our son went to sleep and he told me no because he didn’t feel good. Our son finally went to sleep and I went in our bedroom to get pjs because I was going to get in the shower. He jumped and I asked him what he was doing and he told me nothing well when I went to hug him he told me he didn’t want me touching him because he yet didn’t feel good. His boxers were by his ankles.. and I asked him what he was doing and he yet said nothing. He was lying clearly.... So finally he told me through text that he was doing what I thought he was doing and that this isn’t the first time he’s done this.

So he rather please himself rather than have sex with me.

This makes me feel, unwanted and not attractive to him anymore. He doesn’t get it.
