Which of the following factors increases the likelihood of risky sexual behavior?

The factor that increases the likelihood of risky sexual behavior is the use of alcohol or illicit substances. Substance use can impair judgment and reduce inhibitions, leading individuals to engage in behaviors they might normally avoid. When intoxicated, individuals may fail to utilize protective measures, such as condom use, and may be more inclined to engage in impulsive sexual encounters. This altered state of mind can significantly contribute to decisions that heighten the risk of sexually transmitted infections (STIs) or unintended pregnancies.

In contrast, regular health check-ups and counseling are proactive measures aimed at promoting sexual health and responsible behavior. Health check-ups help individuals stay informed about their sexual health status and encourage safer practices. Counseling can provide individuals with strategies to resist peer pressure, make informed choices, and develop healthier relationships. Additionally, consistent condom use is a behavior that significantly reduces the likelihood of STIs and unintended pregnancies, further demonstrating how preventative measures work against risky sexual behavior.
