So took me a single night to find someone who, for BDSM reasons, has a variety of different types of hospital straps in town. Went over and had them strap me me down just to see how bad wedge may have had it.
If wedge was into bondage, which I can't remember if that's one of the listed forms of BDSM he claims he's into, those straps would've caused one problem, and that's limp dick due to how little they do. They will keep you down during a struggle or a bit of bouncing around, but if you're calm and want out and even remotely an eel, you'll get out of anything I was in.
Most of it you can easily just unstrap yourself since a lot of BDSM gear is modelled after such restraints, he should be familiar with the operation of such things. It's really designed to restrain you while you sleep or if you're mentally in unsound or actually retarded. For sane, stable, health people it's a non-issue.
So this leaves the following possibilities:
a) wedge isn't into BDSM.
b) wedge is into BDSM but not bondage.
c) wedge is into bondage, but isn't even remotely a eel, which means he's likely an incredibly boring partner.
d) wedge is into BDSM and maybe even bondage but is a Dom and not a Sub nor switch.
e) wedge is into bondage and is a sub or switch but is just fucking unhinged and had an actual panic attack due to internalizing his imagined conditions.
Since d) is fucking impossible because troon, that leaves a), b), c) and e). The most charitable of which is b), most likely is a) followed by e), and the most comical is c).
