Is it normal to marry your cousin?
It happens, and whether it’s considered normal or allowed depends a lot on your culture, where you live, and how closely related you are. If you’re first cousins and plan to have children, it’s worth learning about the genetic risks and whether genetic counseling makes sense.
Yes, some people marry cousins, and in some families or cultures it’s an accepted tradition. In others it may be frowned on or legally restricted, so the practical answer depends on where you live and how close the family connection is.
If you mean first cousins, having children together can carry a higher chance of certain inherited conditions than for unrelated couples. That doesn’t mean a child will have a health problem, but a family history or plans for children are good reasons to talk with a genetic counselor or clinician. For more distant cousins, the added risk is generally smaller.
