In comparison with the recent ancestors, over the years, the shape of our body, including the hands and fingers, has evolved to better suit our need for handling objects around us. Does sex contribute to our hand development?

Compared to the other primates, our fingers have shrinked to suit our needs of holding and throwing objects, as ilustrated in the figure below.

Sexual pleasure has had less influence in the evolution of our fingers, but this is because the importance of phisical strength in our hads. Humans rely on their hands to do most of the working activities and less enjoying sex. But this doesn’t mean that the hands have not become more sensitive. In contrast with other animals, we use our hands for sexual pleasure. We love to touch and to be touched by hands. When using our hands to touch the partner’s sexual organ, we get aroused too. Men enjoy touching and squeezing female breasts, and women enjoy feeling the firm butcheeks of a man or his hard cock with their fingers.
As technology will advance, the need to use our hands in working activities will be dimmed. Near future robotic enhanchements will cover our body and make our arms stronger, tougher, while protecting the softness of our skin. As time will pass, our hands won’t be as strong without these enhanchements, and by that time, the nerves in our palms will be much more sensitive. Skin will be much more soft. We will feel every touch. We will be able to have hand-touch orgasms.
