[/INST] Hello,Based on the facts that you have posted it appears that You have been indulged in masturbation since many years and fear yourself to get into problem of infertility in the future.First there is myth in a mind of common man that excessive masturbation is the reason of all sexual problems. But I would like to state that it has been discussed in scientific forums all over the world and proved scientifically that masturbation does not have any negative effect on any organ or system in the body. So do not worry at all.However, it is advisable to get addicted to it. Thank you </s>
