Evolutionary explanations for sexual behavior and orgasm most often posit
facilitating reproduction as the primary function (i.e. greater rate of
fertilization). Other reproductive benefits of sexual pleasure and orgasm such as
improved bonding of parents have also been discussed but not thoroughly. Although
sex is known to be highly reinforcing, behaviorist principles are rarely invoked
alongside evolutionary psychology in order to account for human sexual and social
behavior. In this paper, I will argue that intense sexual pleasure, especially
orgasm, can be understood as a primary reinforcer shaped by evolution to
reinforce behavior that facilitates reproductive success (i.e. conception through
copulation). Next, I will describe an evolutionary account of social shaping. In
particular, I will focus on how humans evolved to use orgasm and sexual arousal
to shape the social behavior and emotional states of others through both
classical and operant conditioning and through both reproductive and
non-reproductive forms of sexual behavior. Finally, I will describe how orgasm is
a signal of sensitivity to reinforcement that is itself reinforcing.
