Final answer:
Several factors can challenge an individual's decision to remain abstinent, including societal and peer pressure, personal relationships, a lack of information on safe sex and STIs, and the personal struggle with sexual orientation. Additionally, personal values, financial status, religion, culture, and significant life events can influence this decision.
Step-by-step explanation:
Factors that are likely to challenge someone's decision to remain abstinent include societal views and pressures, such as the portrayal and acceptance of sexual activity in media and culture. Additionally, personal relationships and peer pressure can significantly influence an individual's decision, especially if abstinence is not the norm within their social circle. Further challenges could stem from a lack of information about safe sex practices and STIs, or a personal struggle with one's sexual orientation and the desire for intimacy or a romantic relationship. Situations that test personal values and moral beliefs, such as those described by Kohlberg, may also push an individual to reevaluate their stance on abstinence. Moreover, the influence of financial status, religious beliefs, cultural expectations, and personal life events, such as parental divorce, can all interplay in the decision-making process around remaining abstinent.
