too short orgasms.. please help! ♥️

M
Hey ladies! So when I am alone and I decide to please myself, it usually takes me literally 10 seconds when rubbing my clit and I start shaking (which kinda hurts as well) and then a little bit later I can't go any longer and I stop. I am pretty sure I cum but it's not that great of an orgasm as it lasts for like 30 seconds. Any advice please??
