Guys & girls: he stroked my arm and said this, is it a positive sign?

We are friends (but I have a crush on him)

we were saying goodbye (he'll be gone for a while)

and he started stroking my arm gently (friendly not flirty)

so I asked him: 'what is it'?

he replied: 'what is it you feel?'.

I was so surprised that I couldn't come up with anything to say.

I'm confused. Is it a positive sign?

Please help me with sincere advice, esp. guys!

Thanks!
