Should there be a class for young ladies (middle and high school age) that teaches proper women's health (sex,periods, etc)?

There are many questions I see that are legitimate questions from young women especially, who don't have a basic knowledge of sex or periods. I feel it would be beneficial for girls to have a class, just for girls, where these things are talked about. Or even female hygiene and care. They may not want to talk about it in normal health classes with boys around. Same for boys. A class where they learn how to take care of themselves and can have questions answered so we have more educated individuals and can better understand their bodies and not get to worried or freaked out over things that are generally normal.
