Hello! I'm 29 circumised. I'm having loss of sensation in penis glans and ed. No libido at all. Meatus is only part where I can feel sensation but it hurts with walking or any type of friction on underwear. It feels like sandpaper. It all started 4 months ago with rough masturbation. Glans skin felt really sore. It never recovered and I lost all pleasure sensation. I started loosing erections shortly after. Could i have caused some permanent damage or this will heal with time?
