Should Anal sex be thoroughly educated on in Sexual education?

Seen this posted this morning by one of my New Jersey friends who was not happy about the "immorality" and "indoctrination" of the new disgusting generation.

My thoughts: I believe that anal sex should be educated on just as oral and PIV sex is. Not only gay couples have anal sex (feel the need to say it because I'm from the bible belt 🥴) so it would suit everyone, and education on bacterial infections, anal fissures, the warning signs of an anal std/sti etc, are good for everyone to learn!

What age should anal sex, and sex in general be discussed if teaching in school is a "no" for you?

If yes what grade set would be most appropriate to introduce the topic to?
