We must proceed from the very concept of virginity and its "loss". The hymen is not a wrapping around the vagina, but rather ruffles that frame the entrance and can be joined in multiple places. During penetration / damage / pressure, they can stretch (and with very rough and sharp impacts, they can break). You can affect the hymen in a variety of ways, and none of them should be classified as "loss of virginity", because the physiological state of "virginity" does not exist in principle. You can think of it as a loss of virginity when you shove something into your vagina, from dick to your toe, or you can think of it as a bad bike ride.
Very unlikely. But, really, it is better not to guess, and in case of a severe injury to the perineum, go to the gynecologist. Rather not even for medical purposes, but not to be thought.
Penetration, in order to tear the hymen, is not necessary, mechanical trauma to the perineum or strong stretching may be enough. But if you have bleeding, it is better not to speculate and go to the doctor.
