Transitioning is the process of changing one's gender presentation permanently to accord with one's internal sense of one's gender - the idea of what it means to be a man or a woman, or genderqueer (in-between). For transgender and transsexual people, this process commonly involves sex reassignment therapy (which may include hormone replacement therapy and sex reassignment surgery), with their gender identity being opposite that of their birth-assigned sex and gender. For intersex people, it is different from how they were raised. For genderqueer people, it is neither solely female nor male. Cross-dressers, drag queens, and drag kings tend not to transition, since their variant gender presentations are (usually) only adopted temporarily.
