Gee, those people. OP, listen to >>11

It can be even healthy for the relationship to have an affair. But, if your boyfriend is like any of those guys above, you might want to hide it from him.

Most people think that monogamy is sacred, but it's actually a social construction. People were not made to live and die having loved just one person in their entire lives. Not even one at the sae time!!! That's a fairy tale.

Now, you have to be very open minded, and feel very secure about what you are doing, or else you might feel remorse after the affair, and that might sully the relationship.
