Well, then, “breach of order” works best for me. Because you should wait until you are married, although I think it is fair to say most of us did not.
I think it's fair to say most of us are sinners in need of a Savior. I think it's fair to say that most of us have done things that are "disordered" either by the nature of the act, or by putting the act in improper context.
I certainly fall into that category.
I think "breach of order" or perhaps "irregularity" is probably the sense in which the original author uses the terms "disordered". At least, that's what I got from it.
