I believed my parents when they said they were moaning because they ordered chinese and the curry was so good
Was it really your parents moaning?
They were having sex obviously.
It's cute that you believed your parents, because they were just trying to protect you. But they can't keep this up forever, you're growing and need to know what truly happens in the bedroom or you'll still be immature.
I am growing up, you are right.
Eventually you will learn about these things anyway. It is better to come from your parents than from somewhere else.
