Hey Tawny, I'm Tawnie too!
You said it right there; organize.
While I've yet to put together my own, I did in one night get 15 hard cocks to come to my place and fuck me good. That was 15 all through the night not all at once.
In my experience secretary work is the key, it will be a little work too. Putting up ads on ALL the sites to cover every possibility available. Party ads where available but run current ones just prior and during the event.
For a while I had a little sissy sub doing it for me but she was hours away from me it was just too complicated.
Or if you can find a like minded pervert, they might be eager to do all of the work just to be a part of it. If you go this route and you don't know this person we'll, keep tabs on what they are posting so you don't get any surprises.
Either way you almost have to go at it like a business. Not to get $, but cock is what you are wanting to get as a return on your investment of time. And you'll want the biggest return for your investment you can get.
Advertise write some copy, write an ad entice that return to invest in you; and stay on top of all of them. Send out group and individual messages, keep them all in the loop. If you're lucky you might get 10% - 15% return on these potential cocks. But it will be worth all of the effort as you are getting fucked senseless...
