Welcome to our forum.
Not 100% sure, but I believe that inside your home you can do anything you want, right in front of your large picture window, but once outside it could become a violation of indecent exposure laws.
I'd stay away from that large picture window if I were you....
2907.09. Public indecency. (A) No person shall recklessly do any of the following, under circumstances in which his or her conduct is likely to be viewed by and affront others, not members of his or her household: (1) Expose his or her private parts, or engage in masturbation; (2) Engage in sexual conduct; (3) Engage in conduct that to an ordinary observer would appear to be sexual conduct or masturbation.
Personally, I've had no problems going au natural for the most part.
We back onto a park and my wife had some privacy concerns. I added some up lighting to the trees from our yard and now the trees look great and the glare from the lights when looking from the park takes care of the privacy.
