Hello, I'm new to mumsnet, but after some advice please. Our AS, 14years old has a gf who is 15 years old. We have noticed that they have been getting intimate, kissing and cuddling each other, but this morning I found some condoms in his bedroom.. also roll ups and tobacco. I am guessing that the gf has given him these. Do I tell the girls parents that I think they are having sex?
