Sexuality in South Korea
Many different factors have shaped the way sexuality is considered across the country. From traditional cultural norms generally accepted by the older generation, to the recent surge of liberalism and westernization – sexual education and sexual behavior have been highly debated topics among South Koreans and continue to be to this day.
Sexual education for teenagers in South Korea has become known for being problematic - not all teenage girls participated in sexual education programs as part of their schooling, and there has been some backlash on the quality of sexual education received by all students. Only half of sexually active teens stated that they always use contraception when having sex.
In 2019, South Korea decriminalized abortion – a move that was praised as moving towards a positive direction for women’s rights and health within the country. Decriminalizing pregnancy termination is particularly important for adolescents - around ** percent of teenage girls who had been pregnant reported having an abortion.
