If there is one sort of consensual sexual relationship that remains stigmatized in our more “open” and “sex positive” and “no kink-shaming” society, it is that between closely related family members (siblings, parent-child, cousins, and even second or third cousins). Interracial relationships are normal (which is a surprisingly recent development), gay relationships have become (relatively speaking) normalized, asexuality is not all that looked down upon (or, if we’re honest, even thought about very often), and so on. But consensual incestual relationships are not. Is there a good reason for continued disapproval of consensual incestual relationships?
