Dear sir
Thanks for your query at DoctorSpring.com
I understand your concern
Most of the times, all such fears are unfounded and usually regress with time. However, a few may have them in reality and supplementation with a multivitamin and vitamin D shall improve the patient. In addition. you can try penile vibratory therapy to strengthen nerves and muscles and increase blood flow to the penis.
Refrain from frequent masturbation.
Take care
Sincerely
Rajiv Goel
