hi..thanks for writing...i have understood your concerns... premature ejaculation does not occur because of masturbation but it is the conditioning that develops after stroking fast and ejaculating rapidly..the way you masturbate is causing this...and there are other causes also..like psychological issues, anxiety and stress.. premature ejaculation can be easily treated with behavioral techniques like squeeze technique, stop-start methods and other interruption methods..you can read them from the internet...but for better knowledge and practice you shud consult a psychiatrist.. your partnet can also help you in practicing it... drugs are also there to treat premature ejaculation...one of them you have taken,,,..paroxetine..these drugs are very useful but on discontinuation, rebound effects can occur... other strategy is of taking as and when required drugs..like dapoxetine...but for usage of these drugs you shud take advice from the expert because they have some side effects also... in my opinion, you shud consult a psychiatrist and ask for help..premature ejaculation is very common..dont take ayurvedic and homeopathic medications...they are not effective.. i hope this advice will be helpful to you..best of luck..
