You cannot reliably or ethically “check virginity” after marriage.
Virginity is not a medical condition and cannot be confirmed by appearance or a physical exam.
The hymen is not a proof of virginity; it can stretch or tear for many non-sexual reasons, or remain intact after intercourse.
There is no valid test that can determine whether a woman has had sex in the past.
Do not pressure, inspect, or test your partner for virginity.
If there are trust or relationship concerns, discuss them openly and respectfully.
If there is a medical concern about pain, bleeding, or injury, consult a qualified gynecologist.
