Safer sex refers to any sexual activities that include precautions against the spread of STIs. This may include the use of condoms during anal or vaginal intercourse as well as during oral sex. The use of a dental dam during cunnilingus or analingus and the use of latex or nitrile gloves during manual stimulation can also protect against STIs. Safer sex may also refer to sexual practices that do not involve the exchange of bodily fluids such as mutual masturbation or frottage.
