If you are considering having children together, it makes sense to seek genetic counseling.
A genetic counselor is a nurse or doctor with special training or expertise who will perform tests and learn about you and your partner's family history.
Legally, you can date and be intimate with your first cousin, but if you are considering marriage, laws vary by state and country. S., some states legally forbid first cousins from marrying, some require genetic counseling before legal union can take place, and other states require proof that at least one potential spouse is infertile.
we call each other the wrong names, but may let us off the hook too - if someone familiar gets your name wrong, it’s because they love you.
