If you're down for Pokemon stuff, I'd love to invite you to check out Pokemon Rapture. It's a forum -- we do our RPing itself on the forum website, but we have a Discord server where we hang out, chat, and plan RP's. (If you want to check us out, the Discord link is https://discord.gg/DNYeeky)
We have an original setting, the Deprin Region, so there's no interaction with canon characters -- every character you'd be RPing with is an OC run by a member of the site. We don't really go into sexual themes, gore, or super dark/gritty stuff; we're more in line with the Pokemon canon tone-wise, though our content tends to be a bit more mature (not in the "sexy/violent" way but simply in the "complex, realistic" way) since we're all adults and our characters are all 16+. Mostly we just RP our characters exploring the region, catching Pokemon, and battling or hanging out with each other.
We're a pretty small group at the moment and we're very chill. If you join up and then decide later it's not for you, that's no problem! We're also quite into worldbuilding and love chatting about how Pokemon (and the disappearance of Pokemon, which is an element of our plot) would affect the development of a society.
