On 27 March 2020 the City of New York issued an official guidance How to enjoy sex and to avoid spreading COVID-19.
An extract of the list:
Have sex with people close to you.
• You are your safest sex partner. Masturbation will not spread COVID-19, especially if you wash your hands (and any sex toys) with soap and water for at least 20 seconds before and after sex.
• The next safest partner is someone you live with. Having close contact — including sex — with only a small circle of people helps prevent spreading COVID-19. Have sex only with consenting partners.
