What term describes a person who abstains from sexual activity?

The term that describes a person who abstains from sexual activity is "celibate." Celibacy typically refers to the voluntary choice to refrain from sexual intercourse, often for religious, spiritual, or personal reasons. It embodies a commitment to live without sexual relations, which can be temporary or lifelong, depending on an individual's beliefs or decisions.

The other terms presented have different meanings, focusing on aspects of identity or expression rather than abstinence from sexual activity. For instance, cross-dressers are individuals who wear clothing typically associated with the opposite gender, often for personal expression or performance, without implications regarding their sexual activity. The term "gay" refers to a sexual orientation where an individual is attracted to members of the same sex, while "transgender" refers to people whose gender identity differs from the sex they were assigned at birth. Neither of these indicates abstinence from sexual activity. Such distinctions underscore why "celibate" is the most appropriate choice.
