Women, you'd be giving up a lot of freedoms, including bodily autonomy, and would be expected to keep a tidy home and tend to your man, but would be provided for.
Men, you'd get all the sex you wanted, and a hot meal waiting for you, but you have to be able to provide for your family.
This would obviously have to limit male applicants to only those who can support a family of 3, and women who can prove they can maintain a house and pass cooking classes.
And of course it would all be voluntary.
