The hymen (the piece of skin in the entrance to the vagina) can break for many reasons, exercise, a hard bump (gymnastics, horse back riding), tampon use, sex or fingering to name just a few.
The hymen is thus not an indication of virginity. Virginity can have two meanings, sexual purity or no intercourse (penis inside the vagina).
As you did not have intercourse, you are technically still a virgin, even though you are no longer sexually pure. This is regardless of the status of your hymen.
Please be careful with sexual play. Rather be safe than sorry.
