Orgasms

So my boyfriend and I have had plenty of sex for the past month( did I mention I lost my virginity to him at the end of last month). And EVERYTIME when he's "done",he asks me if I'm"done". Does that mean did I cum or have an orgasm or something ? If so I dont feel ANYTHING. I've tried to fake an orgasm to make him feel good about himself .. But how do I let him know I don't feel anything ? Or how do I make myself have an orgasm?🤔
