Hi, Welcome to HealthcareMagic Forum.
You mean you Premature Ejaculation
. Kindly do not worry as it is a normal condition and can be controlled. You may want to Masturbate one hour before having sex or when you meet your Partner as it is known to increase your ejaculation time. You can also do Kegel's exercises regularly, where in you contract your Pelvic Floor
Muscles as if you are trying to control your stools or Urine.
Wish you Good Health and Good Luck
