Consciously, no - but that's due to current laws and social traditions. Absent such strictures, the subconscious drive that impels the "clients" to act is 100% based on a desire to reproduce. Men would leave behind 50-100 babies (and burdens to the community) every year without a second thought - that's why cultural traditions evolved as they did.
B.S. It is sexual drive, not the drive to reproduce.
