Actually, YES!
It really depends on what you mean by "virginity".
If you mean = intact hymen as virginity:
Athletic females tear their hymen due to sports or other activities. So when it comes to S ex, it won't bleed since it's already broken. But does that mean that she's a virgin still? depends on your definition
If you mean = first experience at S ex:
Based on what i mentioned above, if the hymen is torn already, then it wont bleed. BUT she is still a virgin because she has never had a sexual experience before.
Another extreme reason is, maybe the guy's ding-dong is too short and can't rip the hymen, so it doesnt break and doesnt bleed as a result.

hahaha possibility lang. HAHAHA
