Hi Everyone, i dont post much here but everyone always seems so helpful and supportive, and Im not sure who else to turn to about this.. I have a little sister who is 14 (15 in feb) - im 25 so theres quite a big age gap but we are still pretty close. Anyway, last time I was home I found a letter written by her to one of her friends.. i know I shouldnt have read it and really regret doing so. The letter mainly talked about her '18 yr old' boyfriend - it talked about how often they had sex etc. I was VERY shocked - Ive always thought of my sis as a very sensible teen. She is very sweet and not at all rebellious - obviously she has the odd strop but in general she gets on v well with me and our parents. The part that really made me feel sick was when she wrote about having sex with 'randomers in the toilet' now her boyfriend had moved to spain. Now I am fairly sure she is lying and trying to impress her friend. Obviously I cant be 100% certain but shes a fairly family orientated girl and doesnt really go out in the evenings/spends saturdays shopping in town like any normal 14 yr old. She is never out in the evenings without my parents knowing where she is. Im almost certain shes lying about the boyfriend as in the letter she said 'my mum is fine with it...' which would certainly NOT be the case! Im just soooooo worried about her now. I had no suspisions she would ever be even thinking about sex, and im worried about her lying to her friends like this. She goes to a fairly 'rough' school and I think her friends are possibly having sex. I dont want to tell my mum as it would really worry her. Not sure how to approach this - if at all - with my sis. Im worried her views on sex are being heavily influenced by her friends, and thats v scary... Any advice?
