Expert's words: The reason you have such doubts is mainly due to the lack of comprehensive understanding of the genitalia. You think the hymen is intact, but it is not. The hymen is like an ancient coin, with a hole in the middle that can accommodate the little finger. When a thick penis forcibly enters, it will tear the hymen, making the hole larger and loosening the annular membrane. Therefore, there is pain during the first sexual intercourse, and there may be a small amount of bleeding. Since you didn't have this feeling that night, it is estimated that the hymen was not broken at that time.
