Shower gel is a kind of cosmetics used to clean the body, which is usually used after bathing. It usually contains some chemical components, such as surfactants, spices and preservatives. Although shower gel can play a lubricating role, it is usually not a lubricating oil specially designed for sexual behavior, which may cause irritation and damage to skin and mucosa.
Stimulating prostate by inserting anus is a sexual act, and special lubricating oil is needed to ensure safety and comfort. Lubricating oil usually contains some components, such as glycerin, silicone resin, wax, etc., which can play an effective role in lubrication and will not cause irritation and damage to skin and mucosa.
Therefore, in order to ensure safety and comfort, it is suggested to use special lubricating oil to stimulate the sexual behavior of prostate, rather than using shower gel or other unprofessional lubricants instead.
