As I said in the other thread...you shouldn't worry. It's actually good for you!
As you orgasm you release endorphins into your body which make you feel good. It releases tension and relaxes you and as far as I'm aware, teenage boys and young men do it pretty much constantly.
It won't make you blind, it won't fall off if you do it too much and it's not dirty or unnatural.
It's your religion and your parents teaching you that it is dirty, that make you feel guilty about it and not just you. Most parents and most religions teach this. It's actually better to release all your tensions and all your sexual frustrations, than to keep them bottled up inside.
Can I suggest that you go to bed earlier and get at least 8-9 hours sleep. Young people still need a lot of sleep as their bodies are maturing every day and they are using up a lot of energy without even realising it. Lack of concentration and being mentally 'off' is caused because you're tired.
Eat healthily. Healthy food helps promote good working conditions in your brain. With more sleep and healthier food, your memory should improve. If, like me, you have a head like a sieve and forget everything...write it down! (I write everything down!)
My last suggestion is to combine these. Go to bed earlier. Masturbate to your hearts content. Find out what you enjoy about sex. How you like to touch yourself. Try to make yourself last longer. Being relaxed about sex and enjoying it make a HUGE difference in a marriage. Where you like touching yourself, women also like to be touched...and kissed. Touching, kissing and pleasuring a woman is a whole lot nicer than just shagging her and she will do the same for you in return.
An orgasm will also make you sleep much more deeply and peacefully and you will be far more relaxed the next day.
Hope that helps.
