Haha funny I just experienced this. Here's my advice..... Wear it like Beckhams with the band when it is in that stage.......it looks stupid if you try to make a 'mini' ponytail, you just have to band it for a few months. After that, you'll be able to do a top knot, but you'll still have some mangy excess behind your ears and at the bottom back. What I suggest is to bobby pin the excess. This was my girlfriend's advice......at first I said no way.... but after she showed me, you can't even tell they're there and it looks super clean. Don't use more than two though, one on each side. You'll have to do that for a few months then finally you'll be able do whatever you want, most likely a complete bun sort of like the guy on Oki-Ni or Nakamura after a good while as his is pretty long. Nakamura's is really good, that's probably the goal of most guys........ Also, of course get your haircut periodically as you'll look like you have a mullet otherwise. Your back hair is going to be a lot shorter than your front as your goal is to grow them out to where they're both even when brushed back completely.

Hope this helps! P.S. Almost all girls like the long hair........A LOT.
