Can I learn about the reproduction process of the opposite gender in school?

I am a young boy and in school they teach us about the female body and the male body. We started learning about growth and development and was wondering if I am allowed to learn about the female orgasm for my own knowledge. Only problem is that it uses a diagram. I don't know if I should not learn about it. **There is a Netflix documentary explaining the “female orgasm” better in depth but I don't know if it would fall under Zina.** Please do help me may Allah set help all of us and keep us safe ameen.
