how to have better orgasms??

so, i have only ever orgasmed by myself with clitoral stimulation. and it only takes about a minute or so. but, i’ve been hearing all these great stories from different women about the ways they’ve found to orgasm and how amazing it is for them. i’ve always felt my orgasms were underwhelming. i also want that mind-blowing experience though. how do i have better orgasms?
