Brief Answer:
DO not worry, there comes no harm from it
Detailed Answer:
Hello my friend.
No, not at all. First as a fellow male, and secondly as a doctor, I am going to be open with you.
Masturbation is very healthy, it helps in the generation and proper functioning of the sexual organs. Whether human body parts or machinery, if something is not used frequently, it does not work as well.
The fact that you feel like masturbating often proves that you have a good and healthy level of testosterone in your body. The more the testosterone, the more fertile you are. There are many men, who cannot have families due to a low
testosterone level. So be thankful, as you are normal and perfectly healthy.
Now coming to the future, the only thing you need to know is that, once you are married, you have to direct all your sexual energy to your wife/partner. At that point in life, masturbation will have to be either reduced to a minimum or completely avoided, as your wife will need all your sexual energy. Other than this, masturbation is perfectly healthy.
Do not believe any of those myths about masturbation causing harm to your physically or mentally. Just stay healthy, and make sure you do not do anything in excess, similarly make sure masturbation is also done in moderation.
Another fact that I would like to shed some light on is that pornography may lead to raising your expectations of sexual intercourse. Don't let that happen. Everything shown in pornographic videos is unreal and unachievable. The women have made alterations to their bodies and the men are all on unhealthy medication, so keep it in mind that real sexual contact and the experience will be very different from what it looks like in these videos.
I am more than happy that you are healthy. This is all that matters. I hope you found my response both healthy and informative. Please feel free to write back to me for any further clarifications, I would be more than happy to help you.
Take care.
