ABSTRACT The present investigation tested the effects of a gene x environment interaction on sexual communication and relational well-being. It was hypothesized that the interaction of variation in oxytocin receptor gene OXTR rs53576 and orgasm would predict post sex communication and subsequent relationship satisfaction. The results revealed that for women in the sample, orgasm was positively associated with disclosing positive thoughts and feelings for one’s partner after sexual activity, which in turn predicted greater relationship satisfaction, regardless of their genotype. The same model was supported for men with the GG genotype for OXTR rs53576, but not for those with the AA or AG genotypes, though the findings should be interpreted with caution due to the small percentage of men who did not orgasm. The findings and their implications for the post sex disclosures model and research on sexual communication are discussed.

基因 X 环境相互作用和枕边谈话：调查 OXTR 基因、性高潮、后性交流和青年关系中的关系满意度之间的关联

摘要 本研究测试了基因 x 环境相互作用对性交流和关系幸福的影响。据推测，催产素受体基因 OXTR rs53576 的变异与性高潮的相互作用将预测性交后的交流和随后的关系满意度。结果显示，对于样本中的女性，性高潮与在性活动后对伴侣的积极想法和感受呈正相关，这反过来又预测了更高的关系满意度，无论她们的基因型如何。对于 OXTR rs53576 具有 GG 基因型的男性，支持相同的模型，但不支持具有 AA 或 AG 基因型的男性，但由于未达到性高潮的男性比例很小，因此应谨慎解释研究结果。
