Detailed Answer:
Dear Friend.
Hi , I am Dr Anshul Varshney , I have read your query in detail , I understand your concern.
See, i can assure you one thing that
Masturbation will not cause a direct harm to your sexual life ever , the harm you can have is by thinking all this.
Trust me , masturbation is a natural act by humans , everyone does it.
It does not make you weak , it doesn't interferes with your sexual life later.
Yes , excess of anything is bad. So , you should masterbate in moderation , that is it should not affect your routine life , your work , your studies.
Performing during actual sex and giving pleasure to your partner is related to so many factors like your feelings for the partner , your confidence.
If you will keep feeling that you won't be able to perform because you used to masturbate , you will definitely have problem in performing.
Trust me , stop thinking all this. Do not take any medicines for this purpose , do not read irrelevant things on google. This is natural act ,you will perform well naturally.
Let me tell you that everyone has loose testicles and slightly deviated penis.
It is just NO ONE accepts this. So , we feel we are abnormal , when we have wrong informations.
Since you masterbate means you get erection , and if you have erection , then there is no problem.
This is my personal opinion based on details available here. If you have any further query, you may please ask me.
Stay Healthy.
Dr Anshul Varshney , MD
