hi.. thanks for writing..i have understood your concerns,, premature ejaculation can be treated with the help of behavioral methods without use of drugs..i feel that you shud practice them and stop drugs..the effects are long lasting and you will find benefit definitely... these techniques are: squeeze technique, stop-start method and other interruption methods...you can read them from internet and practice your partner has also role in it.. it delays ejaculation so you can satisfy your partner and gain most out of it.. drugs are there which are antidepressant medications and they always help but sometimes after stopping them the problem reappears, so in my opinion you shud go for sex therapy by sexologist and avoid using drugs..there are techniques to gain sexual pleasure and spend more time in foreplay before going for penetrative sex.. i hope this advice will be helpful to you..best of luck..
