I tried dating girls my age occasionally but it wasn’t for me. "The biggest age gap was 26 years – I was 22, and she was a customer. She was divorced and had three teenage kids who had left school, and she wanted to get back into clubbing and having fun.
I could tell she was interested as she kept flirting with me. "Our first date was at the Shard, and I took her to France, to nice restaurants and night clubs and bars." Jason admits that his parents hope he will "grow out of this phase".
Suddenly I felt bold; bold enough to mention The Graduate, to talk about Dustin Hoffman, to stumble towards a comparison with Anne Bancroft, the original Mrs Robinson.
Emily grinned and extended a long leg clad tightly in denim.
Baby-faced despite his 30 years, he sported jeans, a striped shirt and a spotless blazer. As the bell went, she was assuring me - not quite convincingly - that I wasn't too old for her. As the bell tolled and I moved from table to table, I realised that every last one of the Mrs Robinsons was well-groomed and svelte.
Some of the other men, however, had not arrived straight from central casting. "It looks like it's at least three blokes to one."Rob was about to ask for a refund when a statuesque blonde walked in. Nadine, a glamorous Frenchwoman whose subtly revealing top was to attract much favourable comment, was more encouraging. There were no grey hairs; there were plenty of low-cut tops. As I sat, or stood, with the older women, I learned a lot about older men.
I shall never know if my own Mrs Robinson was trying to seduce me, humour me or terrify me, as at that point the bell rang - my signal to move on. This was Toy Boy London: "Speed Dater, the UK's biggest speed dating company, invites younger men (aged 23-35) to meet older women (35-50).
Emily was now offering an equally smouldering smile to another, even younger man who was approaching her table. £26, free glass of Champagne on arrival." But how had I come to be here?
Well, somehow, over the years, a succession of attractive teachers and French assistants had managed to resist my schoolboy charms.
Even more bafflingly, when I went to babysit, well-to-do, fragrant mothers had made it clear - very clear - that they really did want me only for my babysitting.
