I am 34 yrs old. From last 6 months i am feeling no such sensations in erection of my penis. It is not even so excited during sexual hours. I have no babies till now. I am so much afraid that recently i have mrd. I cannt concentrate to my partners wish. Also there is lack of interest coming from mastrubation which is not necessary now.. ease suggest any better ideas with proper herbal medication which wont affect my future and my family also. Some years before all were going smooth with my penis. But now i am loosing my confidence day by day. So doctor, please help me to get ride from this situaton.
