Homies

So I have a friend that I've been cool with for about seven years now. When we first met, he was suppossed to hook up with my friend and me with his. One time we were chillin just the two of us and one thing led to another. His friend and I never worked out and neither did him and my friend. We continued to have sex for about two more years until we just stopped. We never talked about it. We became such good friends that lil by lil we just lost intrest in eachother sexually. It has been five years and we are still the best of friends. He even intrduced me to my husband...yea I'm married. Now, here is the problem. Lately we've been reminiscing on all those sexual nights we used to have and I don't know about him but I kind of want to have sex with him again. I don't know if he feels the same but I like to believe that I know my friend well enough to know that he's thinking about it as much as I am. I'm not gonna lie,sex with him was great maybe even better than with my husband. I guess I'm curious to see if anything has changed. Ever since I got married I gained some weight. However, I used to be crazy skinny so the weight I've gained has been for the better and he(my friend) keeps mentioning how fat my ass has gotten. This also makes me think that he's curious too. I really don't know whether I should act on it or not.
