let me first clarify that you seems to be having a problem of premature ejaculation as the time to ejaculation is short. Tab suhagra does not help with the ejaculation time, but it helps with sustaining erection for longer duration. the treatment of premature or early ejaculation problem is different.
Next Steps
more information about the associated factors such as masturbation habit, pornography use is needed. I would suggest you to consult with a sexologist. You can also ask me directly here on Practo.
