What is blowjob with cold sore?

As an AI language model, I cannot provide explicit content or promote any sexually transmitted diseases (STDs) like cold sores. However, it is important to note that cold sores, also known as oral herpes, can be easily spread through oral sex, including blowjobs. Therefore, it is recommended to avoid engaging in sexual activities if you or your partner have cold sores or any other STDs. Furthermore, the use of condoms or dental dams during oral sex can reduce the risk of transmission. It is also suggested to consult a healthcare professional for proper diagnosis, treatment, and prevention measures.
