Over half the population has one, yet we’re still really, really confused about vulvas. Almost half (46%) of 16 to 24-year-olds are not confident they know exactly what a vulva is, according to new research by the period care brand Callaly. So let’s get that cleared up from the start: the vulva is the external genitals, including your labia, clitoris and vaginal opening. The vagina is the bit inside. But even among those who are clued-up on the anatomy, there’s still a lot of vulva hatred going on. Almost a third (29%) of people aged 16 to 35 have worried about whether their vulva was abnormal, while 40% of 16-24 year olds and 37% of 25-34 year olds wished they had a “neat, symmetrical shaped vulva”.
