A nurse is collecting data from a client who is seeking counseling at a mental health clinic. The nurse should identify that which of the following client statements indicates a client concern about sexuality?

A. "I'm uncomfortable when people tell sexually explicit jokes.": Discomfort with sexually explicit jokes reflects personal boundaries and social comfort, but it does not indicate a concern about the client’s own sexuality or sexual function. B. "I feel like my ability to perform sexually has changed since I've gotten older.": This statement directly expresses a concern about sexual function and performance, indicating the client may be experiencing changes in libido, arousal, or sexual satisfaction. It signals the need for assessment and counseling regarding sexual health. C. "I have the same level of sexual desire for my partner as I did in the past.": Maintaining sexual desire suggests that the client does not have current concerns about sexuality. It reflects stability in sexual function rather than a problem or worry. D. "I've been with the same sexual partner for 13 years.": Duration of a relationship provides context about the client’s sexual history but does not indicate a current concern regarding sexuality. It is descriptive rather than indicative of distress or issues.
