That's not a safe assumption (rationally). People often falsely assume that pulling a gun in a confrontation will intimidate the other party. It does not, but instead escalates the scenario beyond recovery.

I've heard/read about that (drawing a gun) before alright, but find it genuinely difficult to equate it to getting my penis stuck in one of these contraptions.

I really don't think that, if in this situation, I'd be too concerned about what happens to the woman in question - I would absolutely be thinking about how on earth do I get out of this thing ASSOONASPOSSIBLE without inflicting any lasting damage.
