You are releasing far too many hormones and neurotransmitters. Thus, your body chemistry quickly changes and you need some time for the the two to elevate. There are many supplements which can help you but the best would be to avoid masturbation or intercourse and anything that would otherwise lead to ejaculation of semen. Whenever you find yourself bored or looking at things which arouse you, avoid it. Keep your mind on other tasks. It takes roughly about a month for the hormones and neurotransmitters to regenerate but it will take longer for them to return to stability. Don't get excited and return to your old ways. Instead, focus on other areas of your life to keep your mind busy and youthful. Avoid processed foods, junk foods, frozen foods, canned foods, coffee, alcohol and sugar. They may provide your body with a quick boost but you will only crash afterwards. If you wish to regain what you once thought you had, avoid these things and begin to eat more whole grain products (rice, spaghetti, bread, nuts), vegetables and fruits (raw), milk products (skim milk, soy milk and low fat yogurt), meat and alternatives (lean ground beef, skinless chicken breast, skinless turkey breast, eggs). If you are truly worried about over masturbation, then focus on your diet more so than anything. After about a month without sex, begin to be more conscious of what you eat and try to eat more smaller meals throughout the day and you'll notice that within that month alone of eating plenty of the things I mentioned, you'll notice great improvements. Also, this diet will only cleanse your body and have your bowels constantly moving to prevent buildup.
