Content warning: coerced sexuality. Originally published in a less structured form here.
In the UK, it has generally been mandatory for sex education classes in state schools to include information on anatomy, puberty, hormonal control of fertility, and the biological aspects of sexual reproduction: namely, penile-vaginal intercourse. (Source: FPA) Information on other forms of sex, on safer sex, on relationships and queer identities and consent and negotiation - all of that is optional. Outside of the school curriculum, 'sex' everywhere seems to be defined primarily in terms of penile-vaginal penetration (I'll just call it 'intercourse' here.) It is called 'real sex', 'full sex' or something else meaning 'the pinnacle of sexual experience.' It is fourth base, it is the only way to really lose one's virginity. This definition is heteronormative, phallocentric, and harmful to most of the population. Why?
