it should be taught in school , you have too know these things , its illogical if you dont teach it,its part of life , i was fine about talking too my parents when i was 11-16, to be honest most kids are , so.... if we didnt learn it in school wed have alot of abortions and the NHS( in the UK) would be bankrupt etc. etc. also , people shouldnt have intercourse until they are fully developed... if people didnt know that then...... yeah , wed have too many kids going too school with their parents lol
