Sorry, but gotta sign off soon, so didn't read. My last test? Two words: Bleach Balls...
Heard about it long ago, and never used it cuz...well, it's poison! Small amount of it, but still. Circumstances pushed me into reverting to actually trying it out.
I was hotter than a firecracker, and passed. Take a Q-tip and break off just the tips. Soak them one by one in bleach (household strength, unscented) or both, if you can handle it I guess. Have a healthy glass of water handy, put it (or them) as far back on your tounge as you can and chug it/them down. If you only did one, repeat. Wait about 30-40 minutes. Drink some more water so You can go when you get there, but not so much you can't wait for them to call you back (I actually stopped off at a public reatroom minutes B4 ariving for the test). When you feel a slightly warmish tingling in the gonads, piss away! Passed with flying colors!
