Okay im almost 15 & the other day I had sex for the first time and I always write everything down in a diary as my councillor told me it could be best and my older sister seen it & went through it & showed my mum & it was a really bitchy thing of her to do & me and my mum had a huge fight over this because of the way she found out... I wasn't ready to tell her and now I think she thinks differently about me what should I do???
