It is the lying and betrayal that I am against, the vowing to be faithful to someone and than going behind their back to sleep with other people.
A person can engage in an open arrangement where their partners are aware of the fact that it will not be a monogamous relationship.
But there is no justification for intentionally misleading another person that you claim to love. If you really loved them, you would tell them the truth about your intentions.
As Scheherazade pointed out. It is not the act of sex that is the main issue, it is the act of breaking a given promise to another person.
If you are not going to be faithful, than do not swear a vow to someone telling them that you are going to be.
