Hey Helium,I read your experience. I am not bissexual and I am in a committed relationship with this guy, and I do love him despite the lack of OS. Now, my fantasy would be to have such an encounter with a very attractive woman, no strings attached. How can you find someone like that? Just for "secs"?
By the way, I doubt you will not see the guy again. When you get bored, you will. You will lead a double life. And even if you choose to hide it from your wife, it will eventually be too heavy for you tod eal with and it will affect your marriage negatively. It's bad when you hold secrets.
