It is not clinically proven that cleaning the glans through toothpaste has the effect of prolonging sexual intercourse. If there is premature ejaculation, it still needs to be treated by medication. At present, the diagnosis of premature ejaculation is more controversial clinically. At present, it is generally agreed that the normal duration of sexual life should be more than 2-10 minutes. If the duration of sexual life is shorter than 2 minutes or less, it can be diagnosed as premature ejaculation. For premature ejaculation, there are also a variety of drugs that can be used to treat it. The first-line treatment for premature ejaculation is currently dapoxetine. Dapoxetine is mainly taken one hour before the start of sex and has a very obvious effect on prolonging the duration of sex. You can also choose sertraline, which is an anti-anxiety drug that has been clinically shown to be very effective in extending the duration of sex.
