Iceland plans on blocking internet porn

Is sexual education really that bad in other countries?
I can't think of any aspect of sex we didn't get covered in sexual education, we went through sex itself, foreplay, porn(including being told about reality vs fiction), how to treat your partner and obviously about STDs and so on, it was a pretty big topic and i think we used 2 straight weeks on it when we were like 13 or 14 years old.

I think we had a 1 hour lesson on male and female reproductive organs and how to use a condom. That was all we got.
