Can you have sex if your partner has a cold sore on his lip

It is generally recommended to avoid intimate contact, including kissing and oral sex, if your partner has a cold sore on their lip. Cold sores are caused by the herpes simplex virus, which can be easily transmitted through direct contact. It's best to wait until the cold sore has completely healed to reduce the risk of transmission to you

Technically you could have sex if you avoid anything oral but I personally would wait until it’s gone.
