Help please

Ok so I masturbate I’ve used my fingers to rub my clit I don’t know if I’ve orgasimed I’ve reached a point to where my whole body like tenses up and i feel like i have to stop it. It feels so good but it takes a while to get to that point and then i can’t do much more. I’m to young for any toys but I have inserted my finger but I don’t get anything. I’ve used a shower head and it works fine I guess but I just kinda want more so idk I need help
