It really adds some spice to our lovemaking. The problem is that the next day we always notice small scratches and bruises on our wrists, which is a little embarrassing. Next, if you are role-playing at all, be certain you have an agreed upon a signal that means you wish to be released. Finally, under normal circumstances you should limit the time either of you is in handcuffs to about a half-hour, stopping sooner if your hands start to go numb. As far as avoiding scratches and bruises, the first thing you need to do is make sure you are using real handcuffs and not cheap ones bought at a novelty store.
Cheap cuffs are generally thinner and have sharper edges.
They are also more prone to become jammed. Next, if you enjoy play struggling, you should make sure to wrap some cloth around the wrists before applying the cuffs. Other than that, use common sense. I know you might not notice it at the time, but try to be careful if you feel any pain. Click on picture above for his bio.
