There is no scientific or reliable way to know if a girl is a virgin just by looking, behavior, or physical signs. Virginity is a social, cultural, and personal concept, not a medical one. Myths about the hymen being intact only in virgins or about bleeding during first intercourse are not universally true. The hymen can stretch or tear due to many activities other than sex, and some women may not bleed the first time they have sex. The only way to truly know is if the person discloses it voluntarily. Any attempt to test or force proof violates privacy and respect.
Some believe behaviors like shyness around sexual topics or awkwardness in intimate situations might hint at virginity, but these are unreliable and not definitive signs. Virginity testing is also widely considered unethical and unscientific by health organizations including the UN and WHO.
In summary, virginity is a private matter defined by the individual, and outside of personal disclosure, it cannot be accurately known or tested by others.
