Does your sense of touch differ from different parts of body?

Indeed it does.

The body has a great number of different "sense of touch" cells. Some sense pressure, some sense texture, pain, heat etc.

The skin where the sensory nerveendings are situated is divided into regions (called dermatomes) depending on what spinal nerve it is connected to. The amount and type of sensory nerveendings in any given area determines roughly how sensitive it is.

The lips, eyelids, fingers and feet are examples of areas that are rich with sensory nerveendings, whereas the back, the front of the thighs and outside of the upper arms are much less so.
