Hi, Welcome to HealthcareMagic Forum.
You haven't mentioned your age? You are suffering from Premature Ejaculation
(PE) and also, may be you have Balanitis
which is the Inflammaton of the Foreskin and Head of Penis. You should get your self examined by a Urologist
, so that he can examine you and prescribe right medications. Do you masturbate, if yes, do it one hour before having sex, this will prolong your Ejaculation time. Also get a Urine routine test done to check for any protein loss.
