Oral sex , sometimes referred to as oral intercourse , is sexual activity involving the stimulation of the genitalia of a person by another person using the mouth including the lips, tongue, or teeth or throat. Cunnilingus is oral sex performed on female genitals, while fellatio is oral sex performed on a penis. Oral sex may be performed as foreplay to incite sexual arousal before other sexual activities such as vaginal or anal intercourse ,   or as an erotic and physically intimate act in its own right. However, the transmission risk for oral sex, especially HIV transmission, is significantly lower than for vaginal or anal sex.
Sex with multiple partners, consecutively or concurrently, is a risk factor for contracting sexually transmitted infections STIs as multiple partner—partner contacts present increased opportunity for transmission. It is unclear, however, if individuals who tend to have more partners also use protection less reliably than those with sexual histories of fewer partners. Longitudinal data can elucidate whether an individual shows a consistent pattern of sex with multiple partners. We identified three trajectory classes described with respect to number of partners as a Multiple, b Single, and c Rare. Trajectory group, relationship status, and their interactions were tested as predictors of using protection against STIs and pregnancy at each wave.
