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.
My wife admitted during Locktober she thinks its hotter when I cum in my cage than in her (she loves getting creampied)...I dont remember the last time I was inside her...6-7 weeks ago? I might have gotten cut off from pussy AND full erections ๐๐ ๏ฟฝ
