Still sounds highly illogical to me. IMHO whether we look at his from an individual motivation perspective, or from an evolutionary biology perspective, it looks to me like either perspective predicts greater, rather than lesser, promiscuity. From an individual motivation perspective, increases in the effectiveness and convenience of contraceptives and improvements in preventing/curing STD's increase an individuals motivation and desire to have sex by reducing the potential for any negative consequences (ie, disease or unwanted pregnancy). On the other hand, from an evolutionary biology perspective, the people who will successfully reproduce are either 1)those who are purposely planning to have children, 2)those who don't use contraceptives regularly or properly, and 3)those who have frequent enough sex that the slight percentage of contraceptive failure catches up to them. :-) In all three cases, but particularly in the second and third, those individuals who enjoy sex and have it frequently are much more likely to pass on their genes than those who don't enjoy it and don't have it regularly. Hence, I would say that the evolutionary pressure to enjoy sex and seek it out will continue as it always has, relatively unaffected by our modern medical advances. :-)
