Women's genitalia is complex, and a lot of people are unsure about just how many holes it has down there. A survey of 1,000 people from Addenbrookes Hospital in Cambridge, England, found that only 46 percent could correctly identify that women have three portals down there. The most common answers were the vagina, urethra, and anus (a.k.a. the "bumhole"), but participants also guessed there were more than that. In the study, participants were shown a diagram with seven annotated structures: labia majora, labia minora, clitoris, mons pubis, uterus, fallopian tubes, and anus, and asked to label as many of them as they could. Free-text responses were allowed, and labels like "peehole" or "butthole" were seen as acceptable if they were descriptive enough.
A thin piece of skin-like tissue called the hymen usually surrounds or partially covers the vaginal opening, which is where a baby exits during childbirth and period blood flows during menstruation. It can sometimes stretch during sex or when inserting a tampon, and the stretching may cause some pain.
The vagina, urethra, anus, and the ovaries make up what is known as the female reproductive system. The ovaries release eggs, and fertilization typically occurs if sperm meets an egg in the fallopian tubes. The fallopian tubes have a finger-like structure called fimbriae that help capture the released eggs, and they lead to the uterus. The anus is where poop exits the body.
