Hello doctor,

I have started to masterbate at the age of 15.now i am 27.
I do masterbate at least 5 days in a week.some times more.
I am scared of getting married as am not sure if am ready for this.sometimes I get stomach ache after masterbate.
I read that pennies gets shrink if over masterbate.is that true??
I really thinking about my sex life after marriage but not sure what's going to happen.
I really wanted to stop masterbate but I could not. Now I am trying my level best to do so.
Can u suggest??
