relearning masturbation

Roselyn
i've been masturbating since i was about 13/14. when i discovered it felt good i used to use shower heads between my legs and basically squeeze my legs around that with the water directly on my clit until I orgasm. I started using my fingers in late high school/early college and i basically do the same thing- i can only cum if i'm rubbing my clit and squeezing my legs together and basically pointing my toes and clenching my leg muscles super tight almost to the point of pain. i've tried masturbating other ways and with toys but it doesn't feel remotely good at all. i tried going back to shower heads and that won't do it for me anymore. even sex barely feels good. is there any way to retrain myself to masturbate another way? or will i basically be like this forever?
