Why do many people still have a virginity complex?

My college classmate Ah Qiang once told me his story.
He was pursuing a junior female student, chasing her for two months,
and she was always hot and cold.
Later, during a gathering, the junior girl drank a little wine,
and reached out and took his hand, and that night they were together.
The first time, the junior girl cried, saying it was her first time,
and asked him to take responsibility.
Ah Qiang was very touched at the time,
and vowed to treat her well.
