I sure disagree, both with your characterization of protected sex with deviance - as in a perverse act. And I point out that you have not proved this from Scripture.
It doesn't deconstruct the Creator's design. It regulates it. I note that God also gave husbands and wives brains and a full understanding of all the circumstances in their lives.
As an example, I have an aunt (her husband is departed now). She got pregnant early in their marriage. She almost died, list the baby, was hospitalized for weeks, and doctors told her not to get pregnant again. She did not. I believe they continued to enjoy the act of married love for the next +50 years. It was not perverse.
(There's about 60 of them listed in the Wikipedia article on "paraphhilias," which is the DSM-VI term for what was previously called perversion. And they don't list them all!!)
What they all have in common, is that they are turned away from what Biblical revelation holds to be good: natural procreative sex. That is, in Biblical terms, an exceptionless norm. See for yourself.
There is not one word in Scripture that authorizes turning sex away from its procreative purpose--- which is what contraception does. That's what contraception has in common with all the other acts which are against natural sex.
