Is it creepy for brother and sister to cuddle on the couch?

As long as he wasn’t adjusting her knobs, I don’ t see the issue.

All physical contact between humans is essentially wrong.

Or in other words yes it is creepy

A brother sitting with his butt in the other’s junk?

Yeah, I don’t know what you would call this, but whatever it is… I’d say it’s taking it to an extreme ridiculous level.

Two adult brothers sitting crotch to butt?

Of course you’re going to think something of it.

Yeah, but those are all very clearly couples basking in each others’ glow. When I think of it with actual brothers and sisters, they’re basically ignoring each other.

My cousins used to sit on my lap all the time, though only one was an adult when it happened. And we’d just carry on a conversation like normal. I know that’s not the same position, but that’s the type of situation I’m picturing. And no one was drunk.

Here’s a picture that I think adequately shows the OP as described: George Michael.
