Oral sex as mate retention behavior

Men perform “mate retention” behaviors to reduce the likelihood of their partner’s infidelity. One mate retention strategy men use is to increase their partner’s relationship satisfaction by provisioning her with benefits. We recruited 351 men to investigate whether men perform oral sex on their partner as part of a broader benefit-provisioning mate retention strategy. In support of the predictions, men who reported performing more mate retention behaviors, in general, and more benefit-provisioning mate retention behaviors, in particular, also reported greater interest in and spent more time performing oral sex on their partner. We present limitations of the research and discuss the benefits of an evolutionary perspective for investigating oral sex as a mate retention behavior.
