Do you get hard when sucking dick?

We assume a tight or small cage will prevent erection? We’ve never been down this road but have talked about it. Getting an erection is my mans biggest fear of a cage!

To me that is the point of putting them in a cage rather be a cuckold, a sissy, a submissive, or even better all three combined. When the cage tube is just long enough so that no matter what position he is sitting in including leaning forward elbows on knees at his softest he will still just touch the end of the tube
