Type of sex and condom use
The type of sex you have (anal, oral or vaginal) and whether or not you use a condom are both related to the risk of getting HIV.
Oral sex is generally a lower risk. Penetrative (anal and vaginal sex) without a condom is generally a higher risk. The risk is highest for the receptive partner in vaginal and anal sex than for an insertive man.
Condoms used correctly protect 100% against HIV transmission and some other STIs. This includes using lube to avoid tears and checking the condom stays in place (see Figures 3 and 4).
When research reports that condoms are only 85-95% effective, this is because people who use condoms do not use them every time.
