Adolescents report using which type of contraception during their first and most recent sexual intercourses?

A) birth control pills
B) spermicide
C) intrauterine device
D) condoms

Adolescents typically use condoms as their primary contraception method during both their first and most recent sexual encounters. This is because condoms are easily accessible, affordable, and offer protection against both pregnancy and sexually transmitted infections. Other methods such as birth control pills, spermicide, and intrauterine devices may require a prescription or medical consultation, making them less common among younger populations.
