Orgasm

So I just recently lost my virginity to my boyfriend of two years about 3 months ago and we’ve been having sex ever since but I don’t think he’s made me have an orgasm. Before him I did use to play with myself but I could never make myself orgasm or even cum and now that I’m with him it’s the same. I’ve never came, squirted, and I don’t believe I’ve experienced an orgasm. Yes I feel pleasure when we have sex but nothing over the top. And the thing is he thinks he makes me cum and orgasm but he doesn’t. What should I do or say without coming off as rude? And also can you guys describe the feeling of an orgasm to me because maybe I have had one I just didn’t know?
