Dude relax… I jerked it twice since I began reading your question.

im a chick and i would do it if i had the time… (myself that is!)

As long as it’s not interferring with your normal day to day activities then I don’t see it as a problem. It’s common for people to masturbate twice a day, and some to only do it once per week.
I wouldn’t consider it an addiction.

no i wouldn’t consider an addiction and not hurting anyone so answer is flat out no. so do it.nothing wrong with porn although i dont watch it.And i dont have a bf and guess what i do too. a teacher said its a need, and u cant deprive yorself if desire and dont have control of hormones.

Masturbation is absolutely normal, even twice per day.

As for not being able to go a day without it–that is slightly more troubling. There is a small chance there is a real psychological issue here, but a good rule of thumb is, if it isn’t hurting you, your relationships and responsibilities, or anybody else, then don’t worry about it.

One reason why you may feel addicted is just the function it serves. You said yourself that it makes you relaxed and focused. Try this experiment: try not to masturbate for the day, and if/when you get to a point where you feel like you “need” to, take a moment to examine yourself. Are you tense? Anxious? Bored? Masturbating would be a solution to all of these problems.

Once you’ve learned an effective way of coping with a problem, you might feel like a compulsion to do it when you encounter the problem. In your case, you may feel a compulsion to masturbate in response to stress or some other trigger because you have learned that it helps. In light of all the other possible “solutions” like alcohol, drugs, promiscuous sex, self-injury, shoplifting, eating disorders, and so on, I think you have the right idea.
