Probably the optimal adaptation, for an average man of modest income and average mental and physical endowments, is the obvious and simple expedient of self-pleasure. Complete reliance upon others for fulfillment of basic needs has pitfalls in today's society, where lawsuits can be filed, charges brought, careers ended overnight.
Technology in the form of Artificial Intelligence will come to the rescue of the many lonely, homely, uncouth men--and women--who seem incapable of finding fulfillment with eager, compliant sexual partners. Robot prostitutes will sell to a vast market, and the value of said market will easily exceed that of motor vehicles. This will arise faster than anyone thinks, because there is bound to be a bright fellow somewhere among the rich who will perceive the same things and pour the necessary investment into crafting an adequate robot-whore that can be sold, rented or borrowed by techno-pimps. Anticipate the next Microsoft.
