guilt over masturbation

i’m twenty and i have never had a boyfriend / girlfriend & i’m a virgin. i started masturbating around 13, and whenever i do it, i feel like something bad happens to “punish” me. i’m old enough to see that’s not the case, but whether it’s my country’s religion or my lack of knowledge in relationships i can’t shake it. like i masturbated a few hours ago and i feel like if my grandpa dies or an earthquake happens.. me, my hormones and throbbing vag are the reasons smh. help me.
