Bleeding during first-time sex, also known as the loss of virginity, is not a reliable indicator of virginity, and not every woman experiences this. The hymen can be broken or stretched before engaging in sexual activity through various ways such as physical activities or personal habits. 

 

The use of a water-based lubrication and taking one's time during sexual activity can help decrease the risk of injury and discomfort. If you have concerns or experience pain or excessive bleeding during sex, you should see a healthcare provider.
