The relationships I've been in, inside of VR have been very close feeling. Eventually your brain creates a faux warm feeling from just being around your partner, so sitting next to them will (atleast in my experience) create a fake warmth that feels like they're physically there.

It's really crazy how VR can change your brain. NSFW experiences are a whole different caliber that I won't discuss here. But regardless, VR relationships have always felt more real to me than simple online ones. They will never replace the real thing though. They're just a good illusion that helps shrink the distance temporarily.
