Yes

I have written four episodes of a series called "Shagging for Scotland" about a mature couple who meet on a flight to Edinburgh and then.......... You can work it out from the title. In these earlier instalments, I have made reference to the women's open bi-sexuality and her ongoing affair with an Italian lover. I thought I would try and write more about this but beyond a simple scenario I cannot seem to flesh it out enough to be another chapter.
I was staying at a Premier Inn in Scotland, there was a conference in town and many delegates were staying in my hotel. The guy in the room next to mine appeared to be at it almost constantly, afternoons and evenings. They sounded like they were different women. He was having a great time.
In a shed at my allotment in a London suburb. It was a tidy shed and I had room for a sleeping bag and a plastic chair. One evening it soon became clear that neither of us was particularly enthusiastic about going home to our respective partners. I had a fire going and offered her some good whisky I kept there. A good conversation, a hug, a kiss and then we went for it. A lovely evening, we both needed the warmth of intimate contact.
