Hello....
Premature ejaculation is a common problem, esply with all the day to day stress one faces, also not so good eating habits, change in lifestyle, etc.
For such treatment I highly recommend you to consult some good Homoeopath nearby who will take a detailed history & suggest certain medicines which will surely help you.

Also do some Pranayam & Meditation which will help you relax & deal with the stress...
