I'm not entirely sure, i thought so but then when she was talking to her mum she a dit she didn't so i guess we're not supposed to know at the moment. :/ - sorry thats not much help! :P
she doesnt seem to be all like" OMG! i did it with some senior who took nude pics of me" so yea. i dont know. but since he took nude pics of her then probably she did have sex.
