My husband manages. But then he has training in submission holds and such, so that may make a difference. He gets clocked occasionally on accident but that just comes with the territory.
But my hands generally aren't free. Just because there is no bondage doesn't mean you are thrashing around like a fish. I'm a flailer too, lol. Generally, you are pinned in a manner that is just as effective (and sometimes more so) than bondage. Or you are pinned in a way that let's you flail *harmlessly*....where all of your thrashing gets you absolutely no where. >.<
You would be surprised at how little leverage you have when being properly pinned, lol. All the strength in the world does nothing if you have no leverage to apply it. And having no leverage is a frustratingly helpless feeling, lol.
