Most people agree that we maintain virginity as long as we refrain from sexual (vaginal) intercourse. But occasionally we hear people speak of 'technical virginity' [...] Data indicate that 'a very significant proportion of teens ha[ve] had experience with oral sex, even if they haven't had sexual intercourse, and may think of themselves as virgins' [...] Other research, especially research looking into virginity loss, reports that 35% of virgins, defined as people who have never engaged in vaginal intercourse, have nonetheless engaged in one or more other forms of heterosexual sexual activity (e.g., oral sex, anal sex, or mutual masturbation).
The social construction of 'sex' as vaginal intercourse affects how other forms of sexual activity are evaluated as sexually satisfying or arousing; in some cases whether an activity is seen as a sexual act at all.

Winkler that kinaidos usually connotes willingness to accept money for sex, as well as habitual passivity [...] In any case, there is no doubt that we are not dealing with an isolated act, but rather a type of person who habitually chooses activity that Callicles finds shameful. That, and no view about same-sex relations per se, is the basis of his criticism. In fact, Callicles is depicted as having a young boyfriend of his own. *The boyfriend is named Demos, also the name for the Athenian "people," to whom Callicles is also devoted. It is likely that the pun on the name is sexual: as Callicles seduces Demos, so also the demos. (It would be assumed that he would practice intercrural intercourse with this boyfriend, thus avoiding putting him in anything like the kinaidos shamed position
