Both of those outcomes seem possible to me. But I don't see that the later is such a problem. Afterall, you get the practice whether they sign your sheet or not and if you need to suck 50 men off to get the five signatories for the first letter (I imagine she plans to send you out to fill more than one) where is the harm? This is, afterall, your new destiny.

You can probably increase your number of signers by only requesting a first name or initials. It seems to me that many of the kind of guys who cruise the peeps at an adult bookstore would not be that willing to sign a document admitting they got a blow-job from another man.
Good luck on you training. I know you will graduate with honors!
