Is Kimberly a virgin?

I believe her to be one of those girls who thinks that oral and anal don't count, and that she was saving herself for Troy... Also, you never see her actually having sex or mention that she had sex with anyone... She is still very innocent and very much a little girl in a lot of ways(reciting a line from a porno movie in order to seduce the lesbian reporter is very 15).. And of course the exposition at the end sounds like a girl who may have missed her opportunity to lose it to someone who she really cared for. That is what makes the character a lot more believable in that she is not some idealized femme fatal/schoolgirl like Buffy in Cruel intentions, but rather a spurned young girl who was saving herself for someone who she was in love with.
