"Would it be the end of the world, if after a few drinks and making out, that you did end up in bed together for some innocent adult fun? It may be just what the doctor prescribes for you to move on more post D."
This kind of casual "adult fun" was not too long ago considered "adultery" or otherwise improper. I guess values have eroded so much. I'd say be true to your good values because that will maintain your self esteem and also be a role model for the kids for whatever it turns out to be worth.
