Among the contraceptive users, the most popular methods are withdrawal and the condom. Boys reported a higher level of contraceptive use than girls. However, their first sexual encounter was more protected than the subsequent ones. In contrast, girls were mostly unprotected during their first experience but were less so in the succeeding sexual contacts. With this behaviour, pregnancy and sexually transmitted diseases among the sexually active youth are most likely to occur.
Fewer factors influence the contraceptive behaviour of sexually active female teenagers.
Most important among these are urban exposure, education and religiosity. This is also true among the highly educated compared to those with only elementary education. Based on the 1982 and 1994 YAFS data, premarital sex levels in females did not change over the last 12 years. The average age at sexual debut is 18 for males and 18.3 for females. For females, the age of first sexual intercourse usually indicates the onset of regular exposure to the risk of pregnancy.
