I think cheating is wrong but I have no problem with my girlfriend if she tells me she wants to fuck someone else. We talk and discuss if one of us wants to sleep with someone else and its fine. The love in our relationship isn't built around sex, sex is a physical act that we both enjoy. The love we have for each other comes from being together, doing things together, talking and interacting with each other.
Couldn't have said it better myself.
On the other hand I am single at the moment and generally I base these things around who I am with, what she is comfortable with. Open relationships are nice, closed ones are nice too, I am happy with either and I wouldn't do anything she didn't want.
Of course that isn't really classed as cheating. Cheating is breaking trust, and if a partner does trust me to be with only her, if I broke that promise it would be very wrong and I'd never do that because I respect my girlfriends.
To be honest, monogamy isn't something that has to be important for anyone who is open-minded enough to realize it is an archaic concept
