Hi there stresseowt, I posted this on another thread, but have copied it here. I understand how you feel, it's a combination of shock (at what your DD is doing), guilt (for looking at her private information) and concern (about her protecting herself physically and emotionally).
I have just discovered (in DD2s room) a leaflet about the morning after pill, advice about the pill and some condoms. She is 15 and has been with her boyfriend for about 3 months.
My experience from DD1 is not to confront her directly as this makes her angry that I have been "snooping" - which I have, and only results in her becoming secretive. Instead I use the knowledge to start a conversation on a relevant topic.
I am a bit shocked about DD2, but I have to put that aside because it is not helpful. She is in the midst of the HPV virus injections at school so I will use that opportunity to have a discussion with her about responsible sex, avoiding STDs etc.
I have been clear with her and her boyfriend that when they stay here they must sleep in separate rooms, and when she stays at his house I speak to his parents to reinforce the same.
I have little choice but to accept that DD2 is probably having a sexual relationship, but I will not condone it in my house, and at the same time I have a responsibility to make sure she is safe.
It's a minefield!
