I'd say that the UK needs Sex Ed...but I'd be a hypocrite. My own high school didn't have Sex Ed. I live in the Southern United States, one of the most religiously backwards places on Earth. When they tried to create a Sex Ed class, hyper-religious parental groups said no and protested until they killed the idea. Cocking Hell, our Science classes aren't even allowed to get into sexual reproduction, be it animal or human. Our schools want students to believe that, when you get married, you ask God for a baby and a stork delivers it to you...Because never once in all my years of school did a teacher ever talk about the concept of a penis, a vagina, and what they do. It was like all my schools honestly didn't want students to know about sex. Fuck, my high school even had a really strict stance on PDA. A teacher saw a guy and girl I was friends with hug and kiss each other on the cheek and they were both torn a new asshole, yelled at about how they shouldn't be doing that stuff at their age...They were 16...
And our community wonders why it is so shocking when there is a teen pregnancy. They don't teach us Sex Ed and they don't even fucking acknowledge the existence of sex in school. We all had to learn about sex ourselves, and I don't think I need to even mention why learning about sex by visiting porn sites is just plain terrible.
