Ever since I was little (age 12) I have had issues with masturbation. Just recently I have become addicted to it and feel that I cannot stop myself and do it every day. I also just recently have become addicted to pornography and watch it as I am masturbating. I feel so helpless and do not know what to do. It makes me feel bad about myself after I do it because I feel that it is wrong and that I should not do it. What do I do?

The question , is porn wrong or immoral , has no definite answer that I have ever heard.

You are by no means way above the average .
But if causes you guilt and stress and loss of control it's time to change.

I suggest you contact a professional counselor or psychologist to help you .
Real addiction is a life shattering and fatal problem at it's worst.

Get a checkup. And while you're there talk to your doctor.
He may be able to refer to a professional.

This is what I would do.

A good measure of a problem, is to think about how it is affecting your everyday life.

If you are pre-occupied, always thinking about masturbation, spending too much time doing it at the expense of other things you would have normally been doing (ie watching TV, doing homework, out with friends etc.), then seeking help as Martin said, is a good idea.

When it is an activity that you cannot control, with consequences that do not deter you, and your day to day life and routine is affected, it may be that the masturbation is symptomatic of stress relief, or poor coping mechanisms to ordinary problems that have become overwhelming.

Take a good look at your life, and see what precedes the masturbation, and if there are any triggers or common characteristics that relate to specific stress or situations going on with you. Not knowing your history, for all we know, you could have social problems, or parent problems, etc.

If none of the above seem to fit the bill, then try to regulate the masterbating activity. See if you have the discipline to schedule every other day for example, or every third day, or once a week. See what you can handle, and think of it more as a reward, than as a shameful problem that you have remorse over, when you do allow yourself to masterbate.

Addiction is a pretty heavy word that is overused when the real issue many times, is simply control, and realization of one's self, in relation to the activity. A person who drinks a beer a day may consider himself addicted to alcohol, but more likely he is addicted to the routine of having one beer a day. Addiction has to meet certain criteria, just like any other problem, physically or psychologically, it is not a term you should assume, simply because you think you masterbate too much.

Consider all the advice and information you have been given, and see if you can't get a better perspective on it, in relation to what goes on in your own world. If it is something, as I said, that you cannot manage, or control, and your life is being negatively affected as a result, then by all means seek counselling.

When you say everyday... do you mean once a day, 10 times a day, or ALL day? Are we talking blisters and or calluses?

Its an important distinction to make.

If you have been doing this since 12yrs, I would guess you do this as your emotional release. For whatever reason it has become your outlet for how to handle different ups and downs in life. Instead of having to face lifes turmoil you do what you have always done and fallen back into taken the pressure off you by masterbating. Its also become your reward factor in your life.
Take the advice of others and get some professional counceling, this is someone who will listen and give advice without any judgement or embarrassment. Its time to learn how to deal everyday stress,pressures,and emotional ups and down in a construtive way, that you can take pride in. You will have to take that step to get over this addiction yourself. Good luck
