also Imperator ... that passage you linked is like ... well SOO confusing i don't know how anyone would say that says anything.
What the passage says is that It's better to not get married and just never have sex, but if you have to have sex, it's better to get married than to "Commit immorality" ie. Having sex outside of marriage.
The reason I referenced that specific passage is that it makes reference to "his wife" and "her husband" as singular nouns, implying that it's not okay to have more than one.
