Boyfriend’s Confession

My boyfriend of a year and I have known each other for much longer as I used to date one of his friend albeit there was a two year gap between them.
We first got together at a party when he spent most of the night coming onto me and I enjoying the attention.
We got talking last week and I asked him when he first realised he actually fancied me and then got the biggest shock when he told me.
He’d always thought of me as his mates girl when we first met but shortly before that party the two guys had been having beers and my ex put on a video he and I had made when we were together of us having sex. I knew he still had it but I didn’t think he would ever be playing it for his friends.
My current boyfriend said he sat there watching it as my ex kept telling him I was the best sex of his life, and he said watching me got him so hard he decided when he next saw me he would try and seduce me.
I accused him of treating me like a porn star but it kind of turned me on to know an old sex tape of me had got him so worked up.
I wonder how many other guys my ex has shared it with …
