You wake up in a laboratory with assorted gadgets and a couple of machines around you, tied to a slanted metal surface, and you try your best to recall what happened previously. Soon you remember, without any sign of just how long it's been since you were knocked out. Once you get a better look at the room, you realize the copious amounts of blood that coats the various tables and the tools lying on these tables. It's your blood. It doesn't take you long to find that someone had been making assorted incisions and cuts on you, and not much longer to realize that you have male reproductive organs.
You start to scream and flail about violently, refusing to accept what's been done to you. It takes quite some time to finally calm yourself down, as you realize that rage will not help you get out of this predicament. You take deep breaths and take another, more analytical look at the room. There was a staircase across the room leading upstairs, it looks like you're in a basement with only one exit. Other than a plethora of scary-looking tools and objects, there wasn't anything distinguishing from this generic room. You glanced at your hooves, they were secured pretty tight by metal rings connected to the surface of what you were on. Insisting that there must be a way to escape, you take numerous glances at the rings constricting you. It was hard to see, but you finally notice a weak point on the ring binding your left rear hoof; the part connecting it to the table was ever so slightly rusted. You start pulling and pushing that hoof with great strength until it finally gives out, leaving you one free hoof.
Just barely reaching it, you managed to get your hoof on one of the tables with wheels and slid it towards you. It was extraordinarily difficult and took several attempts, but you managed to get a bone saw on top of your hoof. Then once around waist level, you kicked your leg up with precision, having it land just barely on the left side of your neck with the sharp part facing away from your skin (thank Celestia!). From there, you were able to just barely get the handle into your mouth, and begun sawing away at the rings on your hooves. It took a whopping 3 hours, but you finally freed yourself from imprisonment.
You started trotting towards the door, freedom, but stopped abruptly. It was quite uncomfortable running around with this, thing, attached to you. It was quite large, but it was also flaccid as well. With this disgusting piece of meat hanging from your mutilated crotch, it would be impossible to run at full speed. Finally putting this thought at the end of your priorities, you get to the door, only to find that the damned thing was locked from the other side.
"Dear Mother of Celestia, are you fucking kidding me?!" you yell out in petulance. It's only now that you realize the huge contrast in your voice from before, it seems as if it is significantly deeper. You took several more nervous glances around the room, this door was the only exit. There must be some way to knock this door down. You look at the scrawny metal tables scattered around the room, surely they would do no good against the reinforced metal door. You're truly stuck here.
What do you do next?
