Perceived Impacts of Partners' Other Relationships on Oneself in Consensual Nonmonogamy.

Existing research suggests a number of both costs and benefits to oneself that can occur as a result of partners' other relationships in consensual nonmonogamy (CNM), but such costs and benefits have not previously been systematically cataloged. Using reflexive thematic analysis, we present themes derived from semi-structured interviews with 51 individuals (63% white, 55% nonbinary/genderqueer/non-cisgendered, and 77% LGBQ) who have practiced CNM, describing the costs and benefits to themselves that they perceive as a result of their partners' other relationships. Themes describing costs include experiencing difficult feelings (e.g., jealousy), having less with a partner (e.g., less of a partner's time) than one would like, difficulties or conflict within one's own relationship, and difficulties or conflict as a result of interactions between metamours (individuals who share a partner). Themes describing benefits include experiencing positive feelings (e.g., compersion), benefiting from a partner getting needs met in other relationships, strengthening of or pleasurable interactions within one's own relationship, enjoyable or beneficial relationships or interactions between metamours, and personal growth as a result of sharing partners with others. We note that these costs and benefits roughly mirror each other, suggesting that they may reflect the positive and negative sides of some fundamental aspects of CNM. Each of our themes also contains a rich range of elements that suggest avenues for future research. Our results suggest that CNM relationships are complex and multi-faceted, and that further research could fruitfully examine the circumstances that influence whether individuals experience their partners' other relationships positively or negatively.

Women's Experiences With Genital Touching, Sexual Pleasure, and Orgasm: Results From a U.S. Probability Sample of Women Ages 18 to 94.

The study purpose was to assess, in a U.S. probability sample of women, experiences related to orgasm, sexual pleasure, and genital touching. In June 2015, 1,055 women ages 18 to 94 from the nationally representative GfK KnowledgePanel® completed a confidential, Internet-based survey. While 18.4% of women reported that intercourse alone was sufficient for orgasm, 36.6% reported clitoral stimulation was necessary for orgasm during intercourse, and an additional 36% indicated that, while clitoral stimulation was not needed, their orgasms feel better if their clitoris is stimulated during intercourse. Women reported diverse preferences for genital touch location, pressure, shape, and pattern. Clinical, therapeutic, and educational implications are discussed.

Olfactory Orientation and Navigation in Humans.

Although predicted by theory, there is no direct evidence that an animal can define an arbitrary location in space as a coordinate location on an odor grid. Here we show that humans can do so. Using a spatial match-to-sample procedure, humans were led to a random location within a room diffused with two odors. After brief sampling and spatial disorientation, they had to return to this location. Over three conditions, participants had access to different sensory stimuli: olfactory only, visual only, and a final control condition with no olfactory, visual, or auditory stimuli. Humans located the target with higher accuracy in the olfaction-only condition than in the control condition and showed higher accuracy than chance. Thus a mechanism long proposed for the homing pigeon, the ability to define a location on a map constructed from chemical stimuli, may also be a navigational mechanism used by humans.

My owner, right or wrong: the effect of familiarity on the domestic dog's behavior in a food-choice task.

Dogs are strongly influenced by human behavior, and they readily form bonds with specific humans. Yet these lines of inquiry are not often combined. The goal of this study was to investigate whether such bonds would play a role in how dogs behave in response to human signals. Using various types of signals, we compared dogs' use of information from a familiar human (their owner) versus an unfamiliar human when choosing between two food containers. In some conditions, the owner indicated a container that gave food and a stranger indicated a container that did not; in other conditions, this was reversed. Dogs more often chose the container indicated by or nearest to their owner, even when this container never yielded a food reward. In two conditions, dogs chose at chance: a control condition in which both pointers were strangers and a condition in which the owner and stranger sat reading books and provided no social signal. This is the first study to directly compare owners to strangers in a single food-choice situation. Our results suggest that dogs make decisions by attending preferentially to social signals from humans with whom they have become familiar.
