The title might be a little misleading, so to clarify, my ex and I had separated 3years ago but her best friend (Lisa) and I were friends before her and maintained some contact after her. Our friendship was a little strained when my ex and I broke up but things had become relatively normal. The events here happened 1 year or so after the break up.
We had met, for dinner and afterwards at a pub, usually with a group of others but this time a bit sparse as it was approaching the holiday season and a bunch of us had gone away already. The leadup isn’t exciting and my memory of it isn’t the best, but importantly we were both a little tipsy (moreso on the drunk side for her) and the rest of the gang had gone off to do their own things. Unsure of how, but the topic got onto my ex and how we had never done the deed – moreso because of her conservative nature rather than a lack of trying. The message must have skewed somewhat however, as Lisa started teasing about how I couldn't get it up for my ex. I gave a flirty response of ‘why don’t you see for yourself’ or something along those lines, she had a small smirk and bite of her lip (or I could have just imagined it) but that was that and the topic changed again.
