Just try it, Love. As you know; if I don't approve beforehand, you'll lose your penis before I slowly kill you.
The answer to the original question posed in this thread is:
YES, it's absolutely possible and totally fine provided that you get your real life partner's consent.
Wouldn't it be far more admirable to be up front and say, "Hey, don't expect me to be monogamous." So that your partner can make the determination as to whether or not she feels compatible with you? I'd *hardly* call it a "slight hurt" if Rago cheated on me. I, personally, would feel absolutely justified in killing him over it. (Now there is fuel for a totally different pot)
Thank goodness he's aware of that! Imagine this scenario, Person A has your view, that cheating is only a slight hurt and we're incompatible if Person B has a problem with it and walks out the door. Person B has my view, and finds that Person A has dipped his stick outside Person B's consent. Do you see where this leads?? Person A isn't going to end up being better off thinking Person B being gone is a good riddance because "we were incompatible and he/she would end up walking out at some point anyway". Person A would be dead and Person B would be in jail. (Yes, I understand that if Rago ever did cheat on me and I killed him that I'd spend the rest of my life in jail, I'm not stupid, just a little on the extreme side.)
