Primary premature (PE) ejaculation is defined as having an ejaculation before 1 minute of the intercourse despite having constant sexual relations, and no control on ejaculation.
While treating the PE, it is very important not to have high expectations such as what is seen in movies.
There are many treatments for PE, starting from behavioral changes, to topical creams, to on demand SRRIs treatment, to daily SSRI.
Usually, we go step by step when treating PE.
I suggest you see your physician to prescribe the appropriate treatment for your condition.
