South Korea [ ] The Criminal Act does not prohibit consensual incest.
Translated by Isabel Denholm Meyer.
Malaysian law also considers sexual intercourse with the stepfamily to be incestuous.
It is illegal for a male to have sexual intercourse with his granddaughter, mother, daughter, sister, or half-sister; and for a female over sixteen years of age with her grandfather, father, son, brother, or half-brother.
Those ads you do see are predominantly from local businesses promoting local services.
