The Need for Sexual Wholeness: Linking Self-Determination Theory to the Physical, Emotional, and Meaning Aspects of Sex.

Sexuality is a highly complex aspect of a human's existence with several elements contributing to a quality sexual relationship. This study examined a broad scope of sexuality encompassing physical, emotional, and meaning aspects of sex, or sexual wholeness. Sexual wholeness is grounded in the idea that a self-determined sexual relationship in which three innate human needs (autonomy, competence, and relatedness) are met is more likely to promote sexual well-being. Using a sample of 884 adults in long-term relationships, we used structural equation modeling to estimate the association between each of the three self-determination theory (SDT) needs and the physical, emotional, and meaning aspects of sex. We found that overall, greater SDT needs satisfaction predicted sexual wholeness, though some needs held more bearing than others and the associations with components of sexual wholeness varied. For women, the physical aspect of sex was predicted by autonomy (predicted comfort) and competence (predicted sexual knowledge) but for the physical aspects of sex for men, no significant associations were found. The emotional aspect of sex was associated with all three SDT needs for both men and women and sexual meaning was associated with competence and relatedness for both men and women.
