I don't know how to riddle but
Riddle me this
I'm a thing that you can hold
When you hold me I am quite hard
But if you hold me long enough I would get wet
What am I?
A human?
Ice cube I think .
A thing that you can hold, when you hold it, it is quite hard and if you hold it long enough it gets wet.
Arthur's dick
Sadly this is not my dick that I know of, everyone has a dick on their side
