Sinful and disordered to me are different concepts. Sin is a religious concept that does not exist for the non-religious who would probably define religious sin in the context of moral (or immoral) or ethical (or unethical) behavior. I think disordered is a good term to describe acts or behaviors that have negative consequences and, while perhaps accepted by society, nevertheless are contrary to what might be best for society.

You are greatly mistaken in your opinion that sin is an idea only. One day, unless you first change your mind, you will encounter a Non-negotiable Rock that will prove how great and far-reaching your error.

It sounds as if you've just described all sexual activity outside marriage (with the possible exception of that kept entirely to oneself, not while watching porn in the public library.) "Disordered" is a very effective term.

“Disordered” (in Catholic moral theology) is another term for “objectively sinful”.
