Hello. I believe we met not long ago.
A certain person has been requesting more.. tactile methods of communication with me - hugs, hand-holding and other gestures that tend to bring people a sense of 'comfort'.
The problem - this 'body' of mine is not made of any matter that mortals could encounter under normal circumstances. Prolonged contact with me kills them.
Perhaps you might have a potential solution? I would appreciate it.
First off I'm going to admit that even though your situation is unique, the advice I'm giving is likely something you've already considered yourself.
That said, first and foremost, communication is your biggest friend. You need to make it clear to your friend that you're not willing to risk their safety for the physical comforting it may temporarily grant to them. If they really care for you the way I suspect that they do, you will be able to come to some kind of mutual understanding.
That said, I'm sure you are aware that you're not the only onceler with superhuman abilities. If you yourself cannot find a way to safely give them a tactile alternative, you might be able to find someone else who may be able to help you find something that could do the trick.
A pet is one option, a puppet that you can control from a safer distance is another alternative. I'm sure you aren't considering a way to "normalize" yourself, but there are countless other alternatives to consider.
I don't know the particulars on how your body negatively affects normal humans, but if it's anything similar to radiation, perhaps a hazmat suit or radiation lead shield?
Let me know if there's any other way I can help! I hope I was at least a little helpful.
