Good skills @astroguy 
I practiced on and off about 5 times. I was watching porn, standing up and was a bit difficult to keep getting hard and lubed up but was good to practice.
The Schlong hasn’t got a straight canal so not sure if the straw technique would work.
Length wise I pretty much fill the whole thing if got in fully erect was very close to the head which was pleasing.
Girth in the normal canal is fine.
But just below the head it has a wider drop down but for some strange reason as not sure anatomically if any Penis is ever bigger there.
They might have thought it was easier to get on having the furthest bit away a bit wider…
Lube me, but of lube inside I slide on and in fine and very painful can use ball strap (tightest ball strap ever!).
Doing a half inside out fold, lube put my head in fold back down working out the air it feels like it should be firm enough to go with no ball strap.
I’m not sure if should cut of ball strap or just leave it there even if I don’t use ball strap.
First time around I might use with ball strap with my wife to make sure 100% fully securely.
Then if pain gets too much, or my wife doesn’t enjoy then I’ll rescue my balls and remove.
If she enjoys can take it and we change position then I still might snatch grab rescue my balls and try it ball loop less.
Main relaxing thing is that it’s a pretty good fit.
Once on doesn’t actually look or feel too massive.
The canal felt warm when I took it off and massive head wasn’t too cold.
I wore it for a while and could still tense my Penis. Squeezing around the side where my head was actually felt quite nice so if that happens whislt inside her would be a bonus.
Once when I was taking it off gave myself a little stroke with it which didn’t feel too bad either.
It could be a good invention if goes down well.
Wouldn’t want to wear it every single time but maybe once a fortnight etc.
Or actually if goes does well and I can still get a good session afterwards then maybe bit more often.
If I have to use ball strap then maybe use less often hehe!
