Are my legs just sensitive?

My artist and I are working on a horror movie themed sleeve on my leg. This is the first time I've had anything tattoo'd on my legs. I could sit for hours on my arms, my chest and my back, but with this leg sleeve I'm on the verge of tapping out after just 2 hours.

We haven't done anything on the inner thigh yet, just my calf, shin and outer thigh and I am dreading that inner thigh work. How was the inner thigh compared to the rest of your leg for those of you that have had something done there? Am I in for a world of hurt here?
