I am not entirely sure about your question either, but I will try to answer it.

STDs can be transmitted through oral sex, so some people choose to use protection. Other people might choose not to, especially if they are in a committed relationship and have been tested for STDs.

When giving oral sex to a man, a flavored condom may be used. When giving oral sex to a woman, a flavored condom may be cut down the side creating a sheet of latex that can then be put over the vaginal area.
