Odd that no one has posted... well maybe not since you want a movie! lol
It is pretty simple really... put the ring around the base of our cock and balls, slide the locking pin through then slide the cage on and lock it all togeather using the spacers on the locking pin to get the right fit. There is a video on the manufacturers website about how to assemble the device.
A lot of people use baby oil to lube up with before putting on the device and still others use silicone based lubricant (where do you get that btw?). Others use nylons to put the device on with out lube (they can explain it better than i).
Hopefully you realize that you can not be hard when putting on the device, right? When i lock up it often takes 15-20 minutes becuase i am constantly waiting for my erections to go down at several points. i also can not lock up with Goddess in the room,as i simply stay aroused the whole time. :boobeyes:
Hope this helps!
