Help.. I told him no- am I the one in the wrong?

Not quite sure what to do.. I gave birth via c section to my baby girl 3 weeks ago. I’m not feeling sexy, & sex is really the last thing on my mind right now. I don’t even want to hardly be touched by my SO. Yesterday though, we had an hour to ourselves, and I wanted to relax, & he wanted to have sex. I told him no multiple times , he still did it. Am I just being dramatic or should I pay more attention to his needs too? I know I’ve been 100% focused on the baby since she’s gotten here, and could be hard for him. Just need some advice.
