Is up to the individuals involved in the relationships to decide these things. What's good for the goose is good for the gander so to be fair, if a man want to have more than one woman, he have to accept that she could have more than one man too. I don't see a big moral thing with how many people you sleep with, the concerns are (1) it's wrong to decieve people who you say you love and (2) STD's are rampant so safety have to be the number one concern- and even if you want take a risk with your own health or possibly life, it's wrong to transfer that risk to someone else. My 2 cents, blessed, raspek 2 all.
