Help orgasm

I was getting eaten out the other day and around 15 minutes went by and I stopped him because I just wasn’t getting anywhere. It felt really good but I felt no where close to an orgasm. I’ve never orgasmed before and when I stopped him he felt really bad because he said that he felt like he didn’t make me feel good but he did. I just feel like it’s a problem with me as I can’t seem to reach an orgasm no matter how hard I try. And I don’t want to make my partners feel bad. What should I do?
