18 doesn't necessarily mean adult content/NSFW content or conversations. It could be due to profanity, mature or violent gameplay, having a drink on stream or just wanting to talk to an adult audience.
I think some people misunderstand what "18 " means
I'm not a lewdtuber.
I don't market myself as NSFW, and my content isn't centered around sexual content
My streams are 18 because they're made for adults.
I swear, I talk about adult life experiences, and I don't want the responsibility of creating content with minors in mind
If you're an adult, welcome.
If you're a minor, there are plenty of amazing creators making content specifically for you.
I'm just not one of them
