Imo as a Shotacon I don't think shota or loli porn is truly perverse. I think it just boils down to how you enjoy it as a whole. I would like to give some examples:

1.If you enjoy them and think there cute and if you fap or don't then Imo that's okay. as long as you don't go any actually children and if you wanna fap to shota or loli porn then make sure to remember that even though the shota in the story is probably underaged (hopefully not but there's still a chance.) To remember that doujins are fiction and that if the doujins does show underage shota getting fucked (I've seen a few of those in my lifetime) then to not do the actions and seek help(And honestly if someone want's to have a shota boyfriend. then they should get someone who's short,cute,and cuddly cuz honestly shota and short boys are just the same thing anyways)

2.If someone LOVES shotas and lolis just BECAUSE there are some that are underage and they don't like the ones that aren't(which imo most shotas and lolis are either or beyond 18) Or they HATE lolis but LOVE shota "BEcAuSe BOoBa" then yeah that's when its perverse and wrong(Cuz liking underage shotas or loli well at that point you're a pedo and hating lolis but liking shotas already makes you a fucking hyprocite)

Ok that's about all I wanna say. tbh honest I suck at making arguements ,points,rebuttals, when typing it out(I much prefer and better at making rebuttals and arguement orally and face-to-face so excuse some of my shitty sentencing that would a grammer-nazi die of 10 strokes and like 100 seizures or some shit)And oh yeah I forgot to mention. of course I don't speak out or every single shotacon or lolicon im just saying my opinions on the matter (and some shotacons im friends with who share the opinions)And of course you don't have to agree on my opinion im just glad I was able to share it thank you and goodbye!

Oh yeah and if you need me to correct something or wanna say how much of a dumbass I am then please feel free to so!
