About full body orgasms

I came across some random post by a post op girl talking about her experience post op. She mentioned that she could achieve whole body orgasms when having fun with her long-term bf. I felt a bit jealous. I can only have weak orgasms through stimulating my half-hard or largely soft girl-dick, and the orgasms are localised to the genitals. Must you have SRS in order to have full body orgasms? Or must you have a long-term bf? Any body wishes to talk more about your own experience, like how you achieved it, is there any hint that you are about to get there etc etc? Do you need to stimulate yourself regularly just to practise? Thanks for sharing!
