Personally yes you should do R-18 scenes but You don't have to make R-18 scenes if you're not comfortable doing them, instead just lead up to the scene than time skip to them doing pillow talk afterwards
you know. I thought about it for sometime now so why don't you try to write some reactions of other YouTube channels and especially one piece related channels like Teking101 or other one piece channels. it will be funny to have reviews about it hahaha
