In two studies (ns = 277 and 221), the authors examined the relationships among sex drive, sociosexuality, lifetime number of sex partners, and gender identity. They found that sex drive is highly and positively correlated with sociosexual orientation, and that both sex drive and sociosexual orientation are positively correlated with lifetime number of sex partners. However, partial correlations revealed that sociosexual orientation is an independent predictor of lifetime number of sex partners, whereas sex drive is not. The authors were also able to replicate and extend Mikach and Bailey's (1999) finding that gender identity is related to women's lifetime number of sex partners. More masculine women had more sex partners and had a less restricted sociosexual orientation than did less masculine women; less masculine men had a higher sex drive than did more masculine men. The findings are discussed with regard to theory and research on sex drive and sociosexuality.
在两项研究（样本量分别为277人和221人）中，作者考察了性欲、社会性取向、性伴侣终生数量与性别认同之间的关系。他们发现，性欲与社会性取向高度正相关，并且性欲和社会性取向都与性伴侣终生数量正相关。然而，偏相关分析表明，社会性取向是性伴侣终生数量的独立预测因素，而性欲则不是。作者还能够重复并扩展米卡奇和贝利（1999年）的研究发现，即性别认同与女性的性伴侣终生数量有关。更具男性气质的女性比男性气质较弱的女性有更多性伴侣，且社会性取向限制更少；男性气质较弱的男性比男性气质较强的男性有更高的性欲。本文将结合性欲和社会性取向的理论与研究对这些发现进行讨论。
