Generally, we classify premature ejaculation into two main categories: primary premature ejaculation and secondary premature ejaculation. Primary premature ejaculation means that the patient has experienced premature ejaculation since their first sexual encounter, and it has always been present. This is referred to as primary premature ejaculation. On the other hand, secondary premature ejaculation refers to those cases where previously, sexual activities were relatively satisfying without incidents of premature ejaculation, meaning the duration of sexual activity was relatively long and both partners were satisfied. However, premature ejaculation developed later due to some reasons. This is called secondary premature ejaculation.
