This is called the "sensate focus" exercise.
Sensate focus is tied in with touching and being contacted. Numerous couples ponder as energizing as wet sand, however in all actuality the craft of contacting and the specialty of being contacted have significantly more to them than a great many people figure it out. One of the methods for augmenting the capability of sensate focus is to start with no assumptions of what you will feel, how great it will be, or how much delight it will create. At the end of the day, regardless of whether the thought doesn't appear to be exciting, you have to begin with a receptive outlook about it, in light of the fact that generally your desires tend to shading your experience and sentiments.
