Orgasm??

I need advice on how to orgasm, I have a pretty active sex life and I enjoy it but my sex drive is pretty low sometimes, like I’m very rarely in that “f— me RIGHT NOW” mood, I can go long periods of time without sex and I feel fine. That being said, when I do have sex, I do enjoy it. There are times that my lips tingly and my legs shake and I’m soooo out of breath but I never orgasm. Sometimes I get really really really wet. I don’t think I know how an orgasm is suppose to feel, maybe I have orgasmed but I don’t know it? I feel bad because my partner sporadically asks if I came or says “cum on me” and I don’t know what to say, I just laugh it off but can anyone give me some tips on how to make it happen or how it’s suppose to feel because I’m a little clueless when it comes to that 🥴
