hi, im 20 last month i was having sex with my girlfreind and my foreskin got pushed back and got suck there, so i went to hospital to get my self sorted. i had to have an injection for the pain and pain killers, the doc sed give it four days before u have sex again, that was ok but since then i have found it difficult to become erect, i thought that was just coz im a smoker so i quit smoking and i can become erect but now its numb i cnt feel a thing not even when i penetrate . please help
