I just dont bother trying any more. Saves a bruised ego.
Mrs T's excuses are legendary. Regardless of what I do for her. They include: IBS, pain in the hip, joggers nipple, tired, got to be up early for work, kids might her us and she is the only woman who has 14-day periods. Before the aisle, it was BJs, CIM/COF, 5-6 times per night, perfume, any room in the house, the full lingerie display, etc.
Now it's chavvy grey pants and vest in bed or Bridget Jones knickers in summer, back towards me and if I am unlucky, an occasional fart.
Punting is more predictable. And enjoyable.
