The biggest advantage is TRUST. It really helps your relationship knowing that your mate is not off doing somebody else while your at work or something.
Then, there is the disease issue, too. If only the two of you are having sex with each other, then you know exactly what diseases you have or don't have, and it stays that way.
No diseases, trust, true love.
