However, couples should try to avoid sexual intercourse during an active episode of herpes, because this is when the virus is most likely to be transmitted. This period includes the time from when your partner first has warning signs of an outbreak, such as a tingling or burning in the genitals, until the last of the sores has healed. Also, sexual activity prolongs the healing of the episode. Transmission risk is increased if there are any breaks in the skin, for example, if you have thrush or small abrasions from sexual intercourse, often due to insufficient lubrication. It can be helpful to use a lubricant specifically for sexual intercourse and avoid sex if you have thrush.
Sexual lubrication is helpful right at the start of sexual activity.
At other times, there is still a small risk of transmitting the infection, even if your partner is showing no signs of genital herpes. If you or your partner has a cold sore, it is advisable to avoid oral sex as this can spread the virus to the genitals. You cannot catch genital herpes by sharing cups, towels or bath water, or from toilet seats. You can still cuddle, share a bed, or kiss. If you too have genital herpes, you may show similar symptoms to those of your partner.
