Should I cheat on my girlfriend?

I have been going out with her steadily for the past 2 years. I really used to like her, and I think I still do. Whatever it is, I do not ever want to break up with her. But at the same time, I can not be limited to just one woman. Would there be a way for me to successfully cheat on her? As in, go with some hot bitchez, sleep with them, have a lil fun and make sure my b*tch never finds out? ;)
