It has been a few years since any of this has happened, and I have since moved away so I feel I can share now. While I feel I can share I also did not want to connect this to my normal account either so this is a toss away account.
At the time of this happening I was teaching high school math. I was a young male teacher and lived in the community that I was teaching in. When I was in school they had always suggested to not do it. Well, they might be right, or they might be just a tad wrong. I assure you that nothing illegal happened. Might blur some ethical lines, but never would I have done anything that really jeopardized my career.
I was living in a townhouse in a community that was a mix of single family homes and well as townhouses. The community had a common pool and gym that the HOA fee allowed one to have access to. I did take advantage of the pool and the equipment. Typically I would work out before school, run home, catch a quick shower and go. There would be a few other adults in there at that time, never would any of the kids be in at that time.
