Yes, it is important to use protection during oral sex to reduce the risk of sexually transmitted infections (STIs). STIs can be transmitted through oral sex, and using protection can help reduce the risk of infection.

There are several types of protection that can be used during oral sex, including:

1. Condoms: Condoms can be used on the penis or inserted into the vagina or anus to help reduce the risk of STI transmission.
2. Dental dams: Dental dams are thin squares of latex or polyurethane that can be placed over the vulva or anus during oral sex to help reduce the risk of STI transmission.
3. Plastic wrap: Plastic wrap can be used as a makeshift dental dam if one is not available.

It is important to use protection consistently and correctly and to follow the instructions for use. It is also important to communicate with your partner about STI testing and the use of protection to help reduce the risk of transmission.
