Unlike the sexual activity of animals, human sexual life is not limited to the purpose of reproduction, but is sometimes conducted for the purpose of friendship to physically confirm human sympathy and mutual affection.

Since this human sexual life can lead to unwanted pregnancies, in most cases, it may be possible to adopt a method to avoid unintentional pregnancies by taking contraceptives or through vasectomy or tubal resection.

However, the contraceptive pill or surgery is likely to cause problems such as side effects, for example, irregular menstruation, infertility, pain, and psychological anxiety.

Condoms are a relatively reliable method of contraception that has been used for a long time in view of the above.

However, depending on the user, the thickness or length of the penis is small, so even when it is relaxed, the length of the penis is less than 4 cm, which is concerned with penile dwarfism, or the sensitivity of the entire genitals including the glans of the penis is too high and the ejaculation time is too short In the case of users, the recently released ultra-thin condoms were often not helpful for their normal sex life.
