What is 21 year old virgin?

A 21-year-old virgin is someone who has reached the age of 21 without ever engaging in sexual intercourse. This is a relatively common occurrence and can be due to a variety of reasons, including personal beliefs, religious values, lack of opportunity, social anxiety, prioritizing other aspects of life such as education or career, or simply not feeling ready for sexual activity. There is no societal expectation or requirement to lose one's virginity at any particular age, and waiting until one feels comfortable and ready is a perfectly valid choice. The decision to engage in sexual relations is a deeply personal one.
