Puberty where we'd be able to start making out the difference generally kicks in around 11, a little later in late bloomers.

Frisk is generally mature for their age it seems, but I presume many people imagine them as exactly that : a late bloomer of late preteen/early teen years

Some countries have minimal age of consent for heretosexual sex as low as 14.

This means in some people's headcanons Frisk may actually be at an age where in their countries he/she would be able to provide consent (or close to that age so a "happens 2-5 years after" story justifies such a thing)

End of story. If you believe Frisk to be below 10, you're very right in feeling icked out by it, but that's not neccessarily the viewpoint of everyone.

Honestly, however, it's just the rule 34 of the internet. And Frisk is the protagonist to boot.
