Yes I also don't agree with underage minors writing smut as well, it's just I've been clogged with people who are adults trying to justify them writing smut ABOUT A MINOR and there's just way too much of it??
I personally agree and don’t think anyone should be writing smut about Tom Holland’s Peter Parker. He’s canonically fifteen. If people want to write smut, there’s a whole roster of grown men in the MCU.
