However, in rare cases HIV can get into the body through healthy mucous membranes. The risk of infection is much higher if the membranes are damaged. The most common artificial barrier is a condom for men. You can also use a female condom to protect the vagina or rectum during intercourse. Fact Sheet 152 has more information on condoms.
Lubricants can increase sexual stimulation.
They also reduce the chance that condoms or other barriers will break. Oil-based lubricants like Vaseline, oils, or creams can damage condoms and other latex barriers. Be sure to use water-based lubricants. Oral sex has some risk of transmitting HIV, especially if sexual fluids get in the mouth and if there are bleeding gums or sores in the mouth. Pieces of latex or plastic wrap over the vagina, or condoms over the penis, can be used as barriers during oral sex.
