You've put a lot more thought into this than me.
I'm recalling a distant, stoned visit to, I think, the sex museum in Amsterdam as my point of reference and am not googling this from work to see how close I am to the reality.

Try
Googling CB-6000. (Hint - It's not a motorbike)

I hope the OP's Mrs doesn't go for the "spoilt orgasm" release, before popping the lock back on and keeping him in there for another couple of weeks. Or giving him a countdown from ten to shoot his bolt, and if he hasn't by then, too late. After 6 weeks he WILL be able to think clearly and the last thing on his mind will be his cock. Enforced chastity brings focus and clarity.

Apparently.

Actually, I hope she DOES... he he

Course it isn't. A 6 litre motorbike? Preposterous.
Having said this, I'd put a few quid on being able to jam that up a coochie, although for the man it wouldn't be much fun.

Never really understood those things...
...on the grounds that they are supposed to prevent the wearer getting an erection. Surely, given sufficient use, one would be 'conditioned' not to get erections - i.e. impotent?

It's about
Power Exchange. You hand over control of your primal urges to your Mistress who decides whether you should become turned on or not, not you, and that is what gives you pleasure.
It won't physically damage you, you'll still get a boner (when SWMBO deems you are worthy). I believe those who enjoy being put in chastity get great satisfaction in knowing they are no longer the drooling, cock-rubbing chimp that 99% of us blokes are, until they have permission to be.

I think the OP's other half should use some CBT devices (once again, nowt to do with motorbikes), it sounds like he's getting too much pleasure from being in chastity, he needs to know he's a BAD boy, and that filth won't be tolerated. My friend "Dr Pinch CBT" manufactures some fiendish devices...

Well, that's up to my wife.
Tease and denial, ruined orgasm are all good fun. Not had much joy with prostate milking. For some reason clothes pegs on the balls makes me cum straight away, which defeats the object.

Apparently spome men can escape those.
Something to do with slipping your balls out or something, sounds too painful to think about. Also, they're relatively cheap.

They say no device is escape proof, but that's not the point.
I don't think many are forced to wear them. I've not got to the point were I've tried or needed to cheat. Some don't use a device and go on honour, even with a device there is still an element of that.
