Vaseline should not be used sexually and it is recommended that people pay attention to sexual hygiene. Vaseline is widely used in medical skin care and industry because of its moisturizing, anti-rust and waterproofing properties. It is worth noting that Vaseline should not be used sexually because it is not a drug and cannot improve vaginal dryness in women or induce penile erection in men. Studies have found that petroleum jelly is fat-soluble and reacts easily with rubber, which can cause condom breakage. Vaseline is not a lubricant and if used during sex, it may increase the incidence of infection, which may have health consequences and should be taken seriously. For people with special needs for sex, they should purchase the product from the proper source, and should also pay attention to abstaining from sex and avoiding unclean sex. It is recommended that people use petroleum jelly reasonably and not abuse it.
