Oh boy, ostentatio genitalium is quite a big and complicated word! But don't worry, I'll break it down for you in a way that's easy to understand.
"Ostentatio" means showing off or displaying something. It's like when you have a really cool toy and you want everyone to see how awesome it is.
"Genitalium" is a fancy word for private body parts. You know, the ones that we're not supposed to show to other people. These include the parts that boys and girls have, like the penis and the vagina.
So when we put these two words together, "ostentatio genitalium" means showing off or displaying your private body parts to other people.
Now, it's important to know that showing our private body parts is not something we should do in public. Just like we have rules about not running around naked outside, we also have rules about not showing our private body parts to others unless it's in a private and safe place.
Showing our private body parts in public could make people feel uncomfortable or even embarrassed. That's why we need to respect each other's privacy and keep our private body parts covered, unless it's with trusted people like our parents, doctors, or caregivers who are helping us with things like using the bathroom or taking a bath.
Remember, it's important to always be respectful of ourselves and others when it comes to our private body parts!
