OMG OMG, I just made out with a married lawyer in the stairwell of my job. Am I screwed?

You and him should be fired. If you guys are working there you should follow the code of conduct. Plus would you like it if you were a newly wed and same lady started kissing your husband at work? Probably not, talk to him and let him know that it has to stop. Yes you might still be attracted to him but get over it, he's not yours.
