As a Mom I found it hard to find the time alone to take long, luxurious baths, and that is one of my little pleasures. Showing with an infant is a very practical way to get clean and it was a bonding experience as well. Bathing works well too. Going on walks and smelling leaves and flowers is a marvelous discovery with little ones too. I remember nature walks with my father as being some of the best quality time when I was little. He made time for me, and it was not hurried or cut off. So, I am offering a list of non sexual pleasures.
Oh and humor helps too.
