I am married to a German, and this is a constant weekly problem. She will continually bring this up....for almost 15 years now. She even shamed the son into doing this. The amusing thing is that German men are starting to look more for Asian women...and you have to wonder why.
I have an easy fix for you.
1. Tie wife up.
2. Gently place her in bath tub.
3. Unzip.
4. Water her well.
5. She'll never complain about you missing the bowl anymore!
