I didn't do my office colleague, but the door was wide open. She was married but in Australia alone, left hubby in her home country. Lots of signals, getting touchy feely during the company Xmas party, asking me to give her a lift home after a late night project deployment, etc. I didn't bite on every opportunity because, while she was hot by office standards, I was already in a "very sexually fulfilling" relationship with a 22 year-old GF at the time.

I thank the heavens every day that I did not go for it. I later found out she had slept with another office colleague from another department at that client, and also had affairs in other companies of my very small industry. Years later, in a big corporate client, she managed to snag an older manager into sending illicit emails to her, and then used that as leverage to get a high position in the company. She's now doing absolutely nothing in her "job", getting paid a huge salary, and can never be fired. Well played....
