If you or your partner have (or think you might have) monkeypox and you decide to have sex, consider the following to reduce the chance of spreading the virus:
Have virtual sex with no in-person contact.
Masturbate together at a distance of at least 6 feet, without touching each other and without touching any rash.
Consider having sex with your clothes on or covering areas where rash is present, reducing as much skin-to-skin contact as possible. If the rash is confined to the genitals or anus, condoms may help; however, condoms alone are likely not enough to prevent monkeypox.
Avoid kissing.
Remember to wash your hands, fetish gear, sex toys and any fabrics (bedding, towels, clothing) after having sex. Learn more about infection control.
Having multiple or anonymous sex partners may increase your chances of exposure to monkeypox. Limiting your number of sex partners may reduce the possibility of exposure.
