Personally I don`t think a child that young should be using the internet unattended anyway. My son is 5 and I have no problems discusing sex or sexuality with him should he ask (and he has) I tell him what is necessary to answer his question in a simple way. Even kids that young hear stuff at school from mates who heard their parents talking or older kids. I feel it`s important for him to know the truth. I also do not want him running around using "gay" as a cuss as many children here do (even his age!) so we have discussed that too. He knows what gay means and doesn`t see an issue. I have gay friends (and am bi) so it`s an important think for me. I do not want him growing up racist, sexist etc so I correct any problems with these issues too. Eg. He ccame home from my parents talking about "bloody pakis" which I find unexceptable so I told him and explained why. I feel it`s better he learn now and grow up with it (so it`s the norm) than have to try and correct any bad learning later.
