Dear service user, Thank you for writing to healthcaremagic. I have gone through your question and understand your concerns regarding erectile problem. You attribute it to masturbation practice. Masturbation in private or with a partner is considered a normal and healthy part of sexual enjoyment. Masturbation is not a disease hence no adverse effects. Masturbation itself does not cause impotency. It is a myth. Let me tell you young friend that there is no such thing as excessive masturbation or over-masturbation. Just as excess of sexual intercourse cannot lead to weakness, so also excess of masturbation. You feel that your penis is not enlarging properly. It seems more due to worries regarding effects of masturbation. Don t worry. So, relax and just enjoy pleasurable sensation during masturbation. Do not focus on size and your performance during masturbation. Lack of knowledge causes anxiety. I recommend counseling with a trained psychiatrist. Hope, I have answered your question. If you have any further questions I will be happy to help. Wish you good health and sex life ahead.
