I have heard before that some people wash their face with toothpaste, claiming that it can whiten and beautify the skin. If toothpaste could really whiten and beautify, then there would be no market for cosmetics and skincare products, and people wouldn't need to spend money at beauty salons. Recently, a claim has been circulating online that applying toothpaste to the glans penis and washing it off can treat premature ejaculation. Can toothpaste really cure premature ejaculation? Let's first understand some knowledge about premature ejaculation. Although the exact definition of premature ejaculation is still controversial, it is usually evaluated by the male's ejaculatory latency period or the frequency of female orgasms during intercourse. When a man loses control over his ejaculation during sexual intercourse, or ejaculates before or just after inserting his penis into the vagina, it can be defined as premature ejaculation; if the frequency of female orgasm during sexual intercourse is less than 50%, it can also be defined as premature ejaculation. Medically, when sexual activity cannot last an ideal amount of time and the penis ejaculates prematurely, it is called premature ejaculation. To treat premature ejaculation, one needs to first find out the cause of the condition. Some patients are affected by psychological reasons, while others are due to organic reasons. Some only need psychological adjustment to recover, while others require both psychological adjustment and medication for premature ejaculation. Blind and incorrect treatment not only does not help in the recovery of premature ejaculation sufferers, but can also lead to unexpected consequences. Can toothpaste really cure premature ejaculation? Let's analyze the ingredients and effects of toothpaste to make it clear. According to what is circulating online, applying toothpaste to the glans penis and washing it off can treat premature ejaculation. Using toothpaste to clean the glans penis can soothe the nerves and prolong the time to ejaculation, thus achieving the purpose of treating premature ejaculation. However, the main components of toothpaste are abrasives, cleaning foam agents, binders, sweeteners, and mint. The component that plays a delaying role is mint. Theoretically speaking, mint indeed inhibits and numbs the nerves around the glans penis, which can play a certain role in delaying ejaculation. Although this method may have some effect, in fact, toothpaste is not a professional drug for premature ejaculation, and doing so carries certain risks and dangers. Besides having a numbing effect, mint can also irritate the already sensitive glans penis of premature ejaculation patients, leading to glans congestion with repeated use. Some people may also experience allergic reactions. Toothpaste's ability to clean teeth mainly relies on abrasives, and repeated friction from these abrasives will inevitably harm the glans penis. If one engages in sexual activity without thoroughly cleaning off the toothpaste, it may irritate the vaginal mucosa, causing discomfort for women. In addition, toothpaste contains chemical components (such as fluoride), which may affect male semen and female fertility, leading to low pregnancy rates or infertility... It is evident that toothpaste is meant for brushing teeth and should not be used to treat premature ejaculation!
