Oral sex

Oral sex is sexual activity in which a person uses the mouth, lips, or tongue to stimulate a partner’s genitals or anus.

Cunnilingus: Oral stimulation of a vulva, especially the clitoris and surrounding genital area. It is the vulva-focused form of oral sex.
Barrier method: A method that reduces exposure to bodily fluids or infectious agents by creating a physical barrier. Condoms and dental dams can reduce infection exposure during oral sex.
Vaginal intercourse: Sexual activity involving penetration of the vagina, commonly by a penis. Unlike oral sex, it can result in pregnancy when sperm reaches an egg.
Human papillomavirus: A large group of viruses that infect skin and mucous membranes; some types cause cancers and genital warts. Oral exposure to HPV can cause infection and is linked to some throat cancers.
Fellatio: Oral stimulation of a penis, typically using the mouth and tongue. It is the penis-focused form of oral sex.
Dental dam: A thin sheet of latex or polyurethane used as a barrier during oral-vulvar or oral-anal contact. It provides a barrier for oral contact with vulvas or anuses.
Anal sex: Sexual activity involving stimulation or penetration of the anus. It may involve penetration, whereas oral sex describes mouth-based stimulation.
Herpes simplex virus: A virus that causes oral or genital herpes infections, often with recurrent sores. Herpes can pass between oral and genital sites through direct contact.
Anilingus: Oral stimulation of the anus and surrounding area. It is the anus-focused form of oral sex.
Condom: A thin sheath worn over a penis or inserted into a vagina or anus to reduce pregnancy and infection risks. A condom can reduce exposure during oral stimulation of a penis.
