Sex and cumming???

So I wasn't sure if I had come or not before during sex and I read something on eve that people said like "if you're not sure if you have came or had an orgasm, then you probably havnt because it feels like..blah blah blah" anyway so what I got from that was that I havnt had an orgasm bc I would know if I have and I told my boyfriend that I haven't had an or orgasm And he said that "you literally screamed more than once and came on me more than once as well" and I haven't ever screamed, only moaned 😂 but what I was wondering, are coming and having an orgasm the same thing?? Bc I don't think I have ever came or had an orgasm but APPARENTLY I have
