The soft tissue that encircles the vagina is known as the hymen. Usually, the first sexual encounter with a girl results in the hymen breaking with the virginity blood capsule. The female may bleed if the hymen leaks as a result of the tissues rupturing or fracturing. When a female's hymen is intact, she is typically referred to as a "virgin." This indicates that a woman loses her virginity if the hymen ruptures during the first sexual encounter, which involves the penis penetrating the vagina.
