A father has turned to Reddit for advice after discovering that his 20-year-old son is in a relationship with his 19-year-old first cousin, a situation that is legal in their state but has left him struggling with how to respond.
According to a report by the Daily Dot, the father shared his concerns in the Reddit community r/NoStupidQuestions, asking how he could express his disapproval without damaging his relationship with his son.
The Situation
In his post, the father explained that his son is an adult who lives independently.
He also noted that the couple did not grow up together and only met a few years ago. Although he strongly disagrees with the relationship, he acknowledged that it is legal where they live.
The father wrote that he wants to continue supporting his son while also being honest about his concerns.
Health Concerns
One of the father’s primary worries involves the potential health risks for any future children.
He said he discussed the genetic considerations with his son, who reportedly told him that the couple does not currently plan to have children together.
Medical experts generally note that children born to first cousins have a higher risk of certain inherited genetic conditions than the general population. However, for a single first-cousin union, the overall increase in absolute risk is considered relatively modest.
Organizations such as the National Society of Genetic Counselors recommend that related couples seek professional genetic counseling if they are considering having children.
Reddit Response
The post attracted significant attention on Reddit, receiving more than 5,000 upvotes.
Many commenters advised the father to maintain open communication rather than attempting to force the couple to end their relationship.
One highly rated response suggested that encouraging genetic counseling would be a more constructive approach if the couple ever decided to have children.
The father agreed with that advice, responding that he did not want to make the situation worse.
Family Dynamics
Several Reddit users also highlighted the potential social impact of the relationship.
Commenters noted that the couple could face ongoing gossip or criticism from relatives and friends, particularly if the relationship becomes long term.
Some suggested that the pair should carefully consider how their relationship could affect broader family dynamics in the future.
Limited Options
A common theme throughout the discussion was that the father’s options are limited because his son is an adult.
Several users pointed out that attempting to force the relationship to end could strain or permanently damage the parent-child relationship.
The father responded that he does not want to become estranged from his son, describing that concern as the central challenge he is trying to navigate.
The discussion reflects the difficult balance some families face when personal beliefs, family relationships and legal considerations intersect. While opinions on the situation varied, many commenters encouraged respectful communication and informed decision-making rather than confrontation.
