Hi I started a new job on Monday. A man came in to the training who I recognized right away, and I think that he recognized me. 4 years ago, several times we used to meet at a gym and jack off together in the showers. I didn't say anything and he didn't either. Yesterday, he asked me if I used to work out at this gym. I said yes, and he said he recognized me. Nothing else has been said since then. I think he is married, and so am I. I would like to see him again and maybe mess around more if possible. How should I proceed? I want to maintain professionalism at work and wouldn't try or suggest anything there. But would like to bring something up, but am afraid of the response. Thanks!
