Recently I had introduced my friend to a social game online. It was supposed to be something fun that we could do together and maybe goof around with. However, things have taken an unexpected turn. I caught my friend having virtual sex with multiple people online. I’m not sure if they know that I know what they’re doing, but now they’re spending more time going in dating rooms, and having virtual sex with people.
Again, I wasn’t expecting this. I’m just worried about my friend, as I don’t think this behavior is healthy… maybe I’m just a judgmental prick. Also, if it helps, we’re 18 years old…

Your friend is a adult. I suggest you butt out of their sexual been wax and attend to your own, before you lose a friend entirely.
Yeah, Im…. failing to see a problem here. If youre both 18 then its perfectly acceptable for them to explore that. If youre upset because them exploring virtual sex means they are spending less time with you then you need to be upfront about that— but dont try to shame them for what they are doing just because you dont understand it, because what they are doing is pretty harmless.
