Hi,
Welcome to HCM.
Masturbation is not injurious to health. Even if you had the practice of masturbation since the age of 10 you would have the ejaculation around 16 years only. Semen is not a precious thing to be lost. Just like any other secretion of our body. You will have sex and semen till you remains healthy.
Your weakness is not due masturbation.(
tiredness mistaken for weakness). If it could be like this, then intercourse also leads to weakness. It is not so. So don't worry and get depressed. This
depression will lead to erectile failure.
Size of penis can shrink when you are in cold climate and becomes normal when you are in hot climate. Bent of penis will not affect your performance. Only the
inferiority complex will lead to problem.
If you have enough confidence and you are still young and 34 years, you can satisfy your wife.
When you go home, don't try to have sex for more than once daily, as you intend to compensate your lost days, it may lead to erectile failure.
Only if you have an urge for sex have sex otherwise don't try to do.
If you have still problem
consult a sexologist.
