Help, Can’t Orgasm!

So I’ve been masturbating for a while now and I thought that I was orgasming but I don’t think I am but can’t tell lol. I get a feeling that I feel like should be cumming but I don’t feel satisfied after and it last for barely a second. also my clit is so sensitive after which makes me think I did cum but honestly I am literally so unsatisfied after! Am I cumming and this is just normal or is something wrong?? pls help :)
