Debih is right - life these days is highly sexualised compared to our childhoods and as parents we have to grasp the nettle. Porn is very easily accessible and I think that children need to be taught that whilst sex is not wrong, women and young girls need to respect their bodies and themselves, and young lads need to be taught that girls and women are not the over inflated, shiny, hairless, totally 'up for it' pliant creatures that appear in porn
Not talking about my own daughter here, she is far more sensible than this, but some of the threads you see between young people on social media make your hair stand up on end - lads often seem to have no respect for girls, talk to them in a highly sexual and often obscene way, ad the girls do likewise to their friends - calling one another 'bitch' as a for of endearment and the like. Appearance and sexual attraction seem to be more important than almost anything else.......
Many parents have no idea how to even start to restrict what their children see on the net - many don't even have basic software or net nannies on their PCs, but even if you do there are smart phone and tablets and ipads......it's impossible to shield children from this completely and they have access to the cyber equivalent of being let loose in a shop full of porn mags and DVDs - we can't stop it so they have to be taught respect for themselves and others, and how to be safe!!
