I’m no longer attracted to my boyfriend.. what do I do?

I just gave birth to our first kid 8 weeks ago. We are also both under a lot of stress. I’ve tried to have sex with him so many times, and I just can’t do it. I have no desire to. I don’t get aroused by him.. no matter what he does. It’s torture when I try to have sex with him because it’s just dry and painful from me not being able to get aroused by him. What do I do? I still love him and want to be with him.. I’m just not really attracted to him anymore.. if that makes sense?? Sex isn’t important to me, but he constantly wants it so I assume it’s somewhat important to him. Please help!
