That is up to you to decide, ones virginity is more of a mental thing than a physical one, the tearing of the hymen does not mean loss of virginity, that depends on how the hymen was torn and how you feel about it. generally speaking, virginity is lost by male penetration and perceived that way by the law, but I think in your case it is up to how you feel about it. In some situations the hymen is not actually torn on male penetration yet she has lost her virginity.
When a woman is raped as a virgin, I think she has the right to claim herself a virgin until she gives herself to her chosen lover, the law may see this differently however.
Interesting subject!!
