If a wife is having a really good time with her black bull, then she needs to know she can stay longer without her husband getting angry.
Actually you and her lover are "like two husbands", and each one has different needs.
She needs the extra time to develop the relationship with her lover because he is new in her life - whilst she has already spent thousands of hours with you.
If you truly love your wife, you will get rid of your temper and rigid time frames. Ask her if you can get a bit of "hot skirt yourself" - to balance things up.
