The period of time of female orgasm aftermath when the man has the free zone to pleasure as he pleases.
“She’s normally not in to butt stuff, but I got it in during the Oh-zone”
“After she got in the Oh-zone, she let me fuck her foot for the first time”
That moment when you climax and you lose control of your body.
You are entering The Oh-Zone!
