Premature ejaculation is a common male sexual dysfunctional disease, usually caused by age, physical condition, psychological or mental factors, and may also be related to diseases of the urinary and endocrine systems. Usually, premature ejaculation can be judged by time, number of times, self-perception and partner’s feeling, etc. 1. Time: at the beginning of the first sexual intercourse, ejaculation occurs before or just after entering the vagina, or after entering the vagina, the sexual intercourse is too short, less than 2-6 minutes; 2. Number of times: ejaculation occurs after entering the vagina for less than 10-30 times; 3.

In the case of regular intercourse, the above symptoms may be suffering from premature ejaculation, but the definition of premature ejaculation is still controversial, so you can let the male physician make a professional judgment. If diagnosed, it can be treated with oral medications, such as phosphodiesterase type 5 inhibitors, or lidocaine or oxycodone gel can be applied to the inside of the condom, which can reduce sensitivity and thus relieve premature ejaculation symptoms.
