In border towns in Nepal, young men who reported drinking alcohol were almost four times more likely to have casual sex than those who did not drink it. Similar associations were observed in Thailand among rural males and urban factory workers, as well as among university students in Seoul, Republic of Korea. School and university students were more likely than others to have practised contraception at debut. However, contraceptive use is not consistent. Condoms are often not used even in contacts with casual partners or sex workers.
Some studies point to inconsistent condom use despite high levels of awareness.
Sexual coercion Thirteen studies document the extent to which sexual activity was forced. Hence the samples, methodologies and age ranges covered vary.
