Sometimes lubricants made of glycerine or silicone, which are safe to use with latex condoms, are available. Clean water and saliva also can be used for lubrication. Lubricants should be applied on the outside of the condom, in the vagina, or in the anus. Lubricants should not be put on the penis, as this can make the condom slip off. A drop or two of lubricant on the inside of the condom before it is unrolled can help increase the sensation of sex for some men. Too much lubricant inside, however, can make the condom slip off.
Do not use products made with oil as lubricants for latex condoms. They can damage latex. Materials that should not be used include: any oils (cooking, baby, coconut, mineral), petroleum jelly, lotions, cold creams, butter, cocoa butter, and margarine.
