All of the people you see above and below have a vagina. However, not all of them identify or present themselves as female. People who don’t identify as female, might be trans men, non-binary or intersex.
People with DSD (Differences in Sex Development), sometimes called intersex people, are born with reproductive organs and genitals that are different from what’s expected of their chromosomes. For example, they have XY chromosomes, usually associated with being male, but their genitals may look different than expected or have characteristics that are associated with being female.
People who identify as trans or non-binary can access specialist healthcare. Terrence Higgins Trust has a directory of resources for trans and non-binary people.
