Girl's Behavior

She pokes me in the butt, torso, and arms quite frequently, and touches my hair. Is this a sign of real attraction?

There's this girl I've know for about a year and a half. She regularly pokes me on my arm, chest, side ribcage, or butt (either to get my attention or something similar). She will also touch the back of my head and has commented that my hair feels soft there a few times.

I'm just confused about what to think. Do I initiate something more? Will I overstep a boundary? I don't have many friends that are girls, I've always grown up in organizations that were many other guys, and in school a lot of the classes I took were predominantly dudes. I feel super awkward when this happens because I have no clue what the proper response is. Any of y'all have ideas?
