Final answer:
Neither partner in a couple with a discrepancy in sexual desire is identified as having a sexual problem; it's an issue many relationships face. The Kinsey study supports this complexity in sexual relationships and those answer choices B, C, and D are findings from the study, whereas A is not.
Step-by-step explanation:
If a couple is experiencing a desire discrepancy, neither partner would be clinically identified as having a sexual problem due merely to the discrepancy itself; it is a common issue in many relationships. The question often arises from different levels of sexual desire between partners, but this is usually seen as a relational or communication issue, rather than a disorder in one partner or the other. So, the correct answer is D) Neither partner; it's a common issue in relationships.
In terms of the Kinsey study findings, the incorrect answer in the given options is A. Sexual desire and sexual ability can be separate functions. Kinsey’s study contributed to an understanding of human sexual behavior and dispelled many myths. It found that sexual desire and sexual ability are indeed separate functions, and it recognized that females enjoy sex as much as males do. It also revealed that same-gender sexual acts were fairly common. Consequently, all other options—B, C, and D—are findings from the Kinsey study.
