Natural-based lubes and lubricants for sexual activities. These are produced from vegetable oil such as nut-oil or corn-oil and will last a long time. They will, however, destroy latex (condoms and some toys), but they do not irritate the vagina, so if your vaginal sex is without latex (completely unprotected), they are long lasting and suitable. Also considered very suitable for masturbation, either sex. See our blog post
