Please note, Asian cultures and very traditional orthodox Christian, Jewish and Muslim communities create a lot of unnecessary guilt and confusion over masturbation and sexuality in general for religious/social/traditional reason that I do not argue with here. Argue unnecessary guilt/shame with your religious leaders... consult doctors for medical questions.
Humans are genetically predisposed to wanting regular pleasure. If you are not getting pleasure from a partner including sex, hugs and general physical closeness you are missing out. Masturbation simply, naturally fills in the gap. Like any other naturally occuring activity we should give it a reasonable time and place in our lives. We eat, sleep, urinate, defecate, socialize, meditate, dream etc etc regularly. Masturbation belongs on that list, how often you do it is up to you and how you live your life. My only caution to you is JUST LIKE EATING, you can over or under do it. JUST LIKE eating and exercising YOU must decide on how much routine and "just enough" variety is required for regular masturbation to fulfill your natural need for pleasure.... to be clear...treat masturbation like exercise for your sexuality.
DO NOT squeeze so hard you scrape your skin or break blood vessels,
DO NOT do it the exact same way every time, DO NOT imagine the exact same things every time,
DO practice ways to maximize your pleasure.
DO imagine life affirming activities and social interactions when masturbating.
DO give your masturbation a reasonable time and place in your life that does not interfere with other things you need to do.
Love yourself the way God/The Universe made you
Have respect for the way your body functions, even if its not 'pretty'
Enjoy the direction you are choosing to take yourself in the future.
