Question: If you put lube on the inside of a condom before sex, is it more likely to slip off during intercourse? What about the outside of the condom?

Latex or polyurethane condoms that are used consistently and correctly are effective in reducing the risk of unwanted pregnancy and transmitting sexually transmitted infections (STIs), including HIV. Adding a small amount of lubricant to the inside tip of a condom will not only help the condom glide on correctly, but the added lube may help increase sensations to the glans of the penis.

A few drops of lube go a long way, using too much on the inside may cause the condom to slip off. For latex condoms, remember to use water or silicone-based lubes. Oil-based lubes damage latex.

Adding lube to the outside of the condom helps avoid excess friction that may cause breakage.
