Women having sex with women, vaginal fluid or blood exchange during
oral sex or other sex play has the potential to infect a partner if one
of the partners is infected. Keep in mind that dental dams are useful at reducing risk in oral sex
performed on a woman (regardless of the gender of the person performing
oral sex), and are also useful in oral-anal sexual contact, a.k.a.
rimming (again regardless of the gender of giver or receiver).Dental dams are a type of barrier method that protect against HIV and other sexually transmitted infections (STIs).
