Loyalty test!! Is he NOT gay after all?? His husband almost caught us!!

I only know my best friend as my gay best friend. But I was always surprised that he said to me that it would be nice to be with a woman. But he had been with his husband for years. Now the day had come when I wanted to know: Is he really gay or is he bi??? Was I the bad guy because his husband could have caught us?? The thrill and the danger were worth it to me 🙂
