You can't really say that he's missing out due to his cage as he would slip out in the position anyway all the time. The cage is the simple and easy solution for him. He does not need to be ashamed of being a bad fuck anymore.
She sat riding her bulls cock with me watching while caged. Trying desperately to get out. I tried to make myself cum by touching the head through the cage which only made it worse. Such lovely pain and discomfort.
