Is my virginity gone?

I am a 17 year old in high school and a few months ago I got molested while swimming in a lake with a group of friends and a lot of people I didn't know. And several guys I don't know grabbed me and started sticking their fingers in my vagina. I have sence then wonder if I lost my virginity. Cause I have always held the belief that really only your husband should be allowed  near that area and your virginity belonged to him. But now I am worried that is gone for me and I have been so afraid of this I am afraid to tell my parents what happened.
