Is masterbation after my gallstone removal for one monrh and 5 days ok for me?

They are unrelated: Normal men, women, boys, and girls masturbate (it's universal). It isn't harmful, as the body goes through similar effects during regular sex with a partner (but too much of anything may become a problem). Masturbation does not relate to gallstone or gall bladder removal, cause hair loss or gray hair, make you weak, cause heart problems, lower testosterone, change your weight, damage eyes, etc...
