Hi, So I'm 18, I Never Had Any Kind Of

hi, so I'm 18, i never had any kind of sexual confrontations other than masturbation,,, now i am struggling with stopping it as after doing it my penis begins to itch and the only way to make that stop is to masturbate even more. This is very tiring and i am worried that this will have a bad impact on my life,,, please help me,,, thank you
