There's a few threads on the catelog that relate to this…I mean, I'll spit one out if you give me something to go off of.
If not, there's not really much to say aside from kids like sex, can feel pleasure from sex, can desire sex, can seek sex, and can understand the basics regarding sex and rather or not they want it, or want to continue when doing it, at the very least, regardless of age (minus infant-tier), as it's not complicated.
There's nothing to really justify with it, as there's nothing bad to try and defend regarding it.
