Dear service user, Thanks for writing to Healthcaremagic. I understand your concerns. Masturbation is similar to sex with female. What your penis do in vagina, it does same in folded hand during masturbation. Sex with female does not cause any health hazards so how masturbation can do...! Masturbation is a normal and healthy part of sexual satisfaction. It does not have any adverse health effects or impotence. The most common reason for this is functional or psychological. It is known as performance anxiety. An occasional episode of erectile failure due to functional or situational reasons like fatigue, tension or own pressure to perform rather to enjoy is very common. This diminishes arousal level and hence erection too. This failure of erection makes one feel I should perform best and he tries to erect’. This in turn further leads to lack of erection. Just enjoy kindling during masturbation without bothering about quality of erection. Practice it regularly. You may have counseling with sex therapist or psychiatrist. I hope this will help you. If you have additional questions then please feel free to write to us. I will be happy to answer your questions. Wish you good sexual health ahead.
