Which behavior is most likely to prevent the risk of STDs?

A. being sexually active with only one person

B. using refusal skills when pressured to engage in sexual activity

C. being sexually active only with asymptomatic partners

B

Explanation:

A is an unwise choice: if the one person you have sex with is someone with STDs, then you will be at risk. C is an unwise choice: asymptomatic partners may experience no symptoms of STDs, but this does not make them people who can't give you STDs. In theory, the very best method of avoiding any STDs is to not be sexually active at all. Even the very best methods of avoiding them have a chance of not working. Thus, B is the best way to avoid any STDs with a 100% chance of avoidance. Involve yourself with the right crowds, and don't let emotions or feelings of connection to another person make you involve yourself with sexual activity before you're married. Even after marriage, you need to ask your partner if they have tested for any STDs.
