Can I keep having sex with an existing partner that I live with? If you’re living with someone and sharing a bed with them, it doesn’t really matter if you’re having sex. If one of you has or has had COVID-19, then the other will have been exposed to it. If you two want to have sex, then you shouldn’t let fears of coronavirus get in the way. Regardless, if one of you has symptoms, or tests positive, you should follow guidance on self-isolation.
