Dear Welcome to HCM We understand your concerns I went through your problem descriptions. You seem so depressed about all these problems. But I feel there is nothing to worry. Every unmarried young adult do masturbation and there is nothing wrong about it. If you are healthy, twice or thrice masturbation during your young age is very well normal. Then as age increases, the frequency decreases. Above 25 it comes down to twice or thrice a week. If you are not at such practice, slowly come to it. No harm will come to human body due to masturbation. But anxiety associated with it can have negatice mental effect. I think you are a victim of such mental problems. Consult a psychological counselor for counseling. Premature Graying of hair is associated with stress and anxiety, which explains your case. Stop worrying about these natural symptoms. Hope this answers your query. Available for further clarifications. Good luck.
