Sociosexual Orientations

From u/MerryVegetableGarden:

Unrestricted vs Restricted Sociosexual Orientations

Unrestricted SOIs:

•	⁠more willing to have casual sex and are more comfortable engaging in sex without love, commitment or closeness.
•	⁠exhibit sexually permissive attitudes and have had a high number of past sexual relationships, and are more likely to engage in infidelity (Feldman & Cauffman, 1999)
•	⁠Individuals with an unrestricted sociosexual orientation (SO) are less committed to their romantic relationships and more likely to engage in infidelity
•	⁠highly correlated with number of casual sexual partners
•	⁠those with history of infidelity, compared with those without, have a relatively unrestricted SO.
•	⁠those with an unrestricted SO are generally less committed to their romantic partners (Jones 1998; Simpson & Gangestad, 1991), and low commitment is often a predictor of infidelity (Drigotas, Safstrom, & Gentilia, 1999).
•	⁠those with an unrestricted SO are often looking for new, attractive partners (Simpson, Wilson, & Winterheld, 2004).
•	⁠a slightly higher proportion of the unrestricted phenotype is present in both sexes (males approx. 62%, females approx. 50%).
•	⁠approximately half of the men and women in the top (withinsex) quintiles of sociosexuality had been sexually unfaithful to a steady partner; this was more than a tenfold increase over the corresponding rate for people in the bottom quintiles. Sexual infidelity is a common cause of divorce cross-culturally (Buss, 1994)
•	⁠Sociosexual orientation is stable throughout one’s lifetime. It is very unlikely for a sociosexually-unrestricted person transition to a sociosexually-restricted one. Like <1%.

Restricted SOIs

•	⁠less willing to engage in casual sex; they prefer greater love, commitment and emotional closeness before having sex with romantic partners
•	⁠Women who value commitment much more than male quality have a restricted sociosexual orientation, and women with opposite preferences have an unrestricted orientation.
•	⁠engage in sexual behaviors within the context of a close and committed romantic relationship


Essentially, if guys want sex without investment in a woman, they pursue those with unrestricted SOIs. If you want a faithful long-term partner, you pursue girls with restricted SOIs: the innocent and trusting ones that are incredibly precious, to be cherished and valued. The Madonna-Whore complex is highly accurate.

There are good girls and sluts (not using that word negatively, just as a descriptor), and whether a woman is one or the other is a relatively fixed thing throughout life. They both have their uses: one as a life partner that you’d give your life for and the other for a great time, without any expectations of fidelity, loyalty, or exclusivity because these types WILL cheat on and divorce you in long run.
