"We were 17 and I'd snogged her for about five hours on the sofa, but the next day when we met up, I had this realisation that this wasn't such a good idea.
"I could sense she was keen so I suddenly came out with this amazing story.
"I have no idea where it came from. I told her I had a girlfriend in England and had just found out she was pregnant, and that I couldn't really have another relationship.
