I think most do, do they not? Physical intimacy can be so much more ...mmm... intimate and pleasurable when there is a connection.

It needn't be as deep as love, only as deep as one individual fully recognizing another in the moment.

Or, if I may put this another way, having a soul makes a person better at the line of work you are describing! Alas, there is naught you can do about that short of hiring from among the Chosen and I fear few will take you up on that offer. So your business must always be substandard at best. What a shame.
