Sorry, but that to me is a ridicilous statement. Intelligence in this business does not mean that a woman is boring and can not please. It simply means that she is intelligent enough to get a feel for what you need.
You would be supprised how many man (who are sexualy healthy) are also lonely and in need of someone to make them feel special. How many hours I have spent listening to the things the wife doesn't want to hear.
Non the less, if you only wish for an object of your lust....those are easy to find for a very low price. Makes you wonder though if those women are D&D free....after all low cost means higher turn around rate.
