Well, I can see your point, but I think children shoul be made gradually aware of sex and all it's implications - and from a reasonably young age. I wouldn't sit my ten year old down at the computer and tell him to find out what he can about sex as there's just far too much information out there - and with no background knowledge, how do you even know what to look for? I think a parent should give the basics, answer questions a child might have, then if they want to research further, then that's fine.
As an adult, then yes - no way do you need to talk about sex with parents!
