|Abstract||Oral sex is a broad term that includes fellatio (oral contact with the penis), cunnilingus (oral|
contact with the vagina), and anilingus (oral contact with the anus). It’s difficult to establish
the actual risks associated with these forms of oral sex, and the contribution they may make
to the overall number of newly diagnosed cases of HIV or other STIs within the UK. This is
generally because it is rare for people to engage in oral sex in isolation from penetrative anal
or vaginal intercourse as these are the primary routes by which HIV and other sexually
transmitted infections (STIs) are spread.
