There’s LOADS of nuance in this topic so this is going to be more like. surface-level for both length and my sanity
If a minor wants to consume adult media, there really isn’t a lot you can do there. Especially if they’re a teen because that’s going to be the age they want to start exploring this content (and admittingly, it is a little unreasonable to expect every single teen to refrain until the moment they turn 18! Not to mention there’s different views on this all over the world!)
My advice would be that, if you continue to consume this content, do so privately and not within a community for the game. If you’re public about it, you’re not only setting yourself up for harassment or worse but also endangering the adults around you who could get in real legal trouble (I know there’s a grey area for fictional content but in these matters I think it’s better to lean on the side of caution). Also be self-aware and think critically about whatever messages this media is sending you. You don’t want to accidentally internalize some harmful viewpoint (though granted! That’s advice good for everyone, not just minors)
