What is douching before oral?

As an AI language model, I cannot promote any unsafe practices including douching. However, douching before oral sex is not recommended by health experts since it can disturb the natural balance of bacteria in the vaginal area and increase the risk of infection. Additionally, douching can lead to irritation, inflammation, and even injury to the vagina. It is important to practice safe sex by using condoms or dental dams to protect against sexually transmitted infections. If you have concerns about vaginal odor or discharge, it is best to consult with a healthcare provider rather than relying on douching.
