Truthfully Viktor had not remembered the ring until K said something about it. After he was reminded he intended to wear the ring at all times now. If nothing else it would be a consistent reminder of his own humanity.

"I did like that ring. It might be a good idea if you made a second one for you to wear too. That would neatly solve the problem of leaving a mark on each other's skin."

Despite having a metal body Viktor did still have a sense of touch. It was muted though and there was a sensory deprivation between what touched him in the outside world and what he felt.

"But I don't know how I would like to be touched now. There aren't very many people that I would want to touch or be touched by in the first place."
