matrimonial blindness 

A rare condition that your partner expects you to have. When you become married/in a serious relationship, they expect you to become blind toward everyone but them. In other words, they would rather your eyes linger on no one else's boobs but theirs.

Sally: Tom! You're supposed to have matrimonial blindness!

Alternis sexus matrimonium 

When two people of different gender get married, while one chooses to change his/her gender during the course of the marriage, but the two remain married despite it causing confusion over the sexual preference of the two.

Now that Bob and Sue became Linda and Sue; Does that make them alternis sexus matrimonium?
