Please be gentle with me as i am feeling rather sick & queasy. Ds only just 13. Just put my head round door and found him 'doing the deed' whilst looking at his mobile phone. i wish i hadn't. I don't think he saw me. Is this not a little young or am i just being naive? He has not shown any interest in girls at all. His phone has a password, after i recover from my shock i am going to think of what i can do to block unsavoury sites. Is 13 not too young though??!!
