Other safer sex practices
Sex toys and vibrators that are shared between sex partners should be covered with a latex barrier (condoms) or washed with soap and water between partner use.
Fisting, the insertion of fingers or hand into the vagina or anus of a partner, can be safer if the person inserting wears a latex glove as a barrier to the possible transmission of disease.
There are many non-penetrative activities that carry little or no risk of disease transmission, such as dry humping and mutual masturbation. These can still bring great pleasure to sex partners wanting to reduce disease risk but still share pleasurable sex play.
The daily use of certain medicine (e.g., PrEP) may help prevent the transmission of HIV.
