Numbness after c-section???

I hear a lot of woman have never experienced an orgasm and I feel like I'm one of them. I had my child when I was young and it's been almost 10 years ago and I had only been with one guy before I got pregnant so I don't remember if I had an orgasm. My husband now says I do have an orgasm when we have sex but I can't feel it and I think it's because I'm still kinda numb by my scar. Is this true? Or is there anything I can't try to where I can feel or experience it?? I just feel like I'm missing out and my husband really wants me to feel it. Please give me any kind of advice !!!!
