If this is my world I actually think you could break the place into chapters female, male and home.
Female – this refers to female and girl situations such as first bra, period knickers, nights in and ladies day at Ascot.
Male – stepping up a gear to be slightly more risky and sexy with planned nights of love, little gifts which are given and have been plus seduction techniques which have gone both so right and so wrong.
Home – reflecting everyday life from washing smalls, birthday suit on a hot summer days in the garden to relaxing at home in winter.
I think that just about covers most things. I will add to this later if I find anything missing that could be covered in a separate chapter..
