Yes! Herpes Simplex Virus can spread from your mouth to your partner’s genitals during the performance of oral sex activities such as analingus, cunnilingus or fellatio. It becomes a situation where it can be described technically as genital herpes.
Herpes is the most common viral condition that can be transmitted as an STD through oral sex. Herpes Simplex Virus 1 causes cold sores around your mouth and lips and Herpes Simplex Virus 2 causes sores around your genitals. When a person with HSV-1 gives oral sex to someone, the virus can spread to the genitals of the other person. This can also apply in reverse when HSV-2 can be transmitted from the genitals to the mouth of the other party when performing oral sex. It has been reported that 50% of all new cases of infections of genital herpes are as a result of HSV-1.
To give you an example, if your girlfriend has a cold sore or even an invisible symptom of HSV-1 and engages in oral sex with you, her herpes virus will be transferred to you and it could affect your mouth or your genital areas.
You can use a latex barrier such as a dental dam or a condom when you perform oral sex. It will help in protecting you and your sexual partner from spreading herpes if one of you is infected by the Herpes Simplex Virus. Precaution such as this can work when activity involves only those areas where there is a possibility of the virus being shed. When your partner or you have sores that are visible on the genitals, you can take a decision on whether it would be advisable to go perform oral sex. It will also apply when one of you has cold sores on his or her mouth.
Contagious Properties of the Virus
It is always important to know that Herpes Simplex Virus is contagious despite the symptoms being visible or hidden. The infection usually begins after five days once a contact is made with the virus and the early symptoms involve irritation. This is soon followed by an outbreak of blisters. The outbreak of such ulcers will last for few days until they scab over gradually. They will heal in about a fortnight. The initial attacks of both genital and oral herpes after oral sex will probably be the worst one. Recurrence may occur in some cases and it will be milder, particularly if the infection is caused by the virus that gives cold sores or HSV-1.
As long as a person does not have cold sores on the mouth, oral sex can be performed on the partner. Even when there is an outbreak of some genital symptoms, there are several ways of expressing yourself sexually without the need for mouth to genital or genital to mouth contact.
