Hey, grow up!
I say let it grow. I'm a guy with long hair, and plenty of people tell me to cut it, but screw them. I like my hair long. I figure I should keep as much hair as I can since I can tell my hairline has started to recede somewhat.
Since you are currently in the "no man's land" of hair length, you shoud use gel or something. I used the cheapest gel I could find and combed it back like Steve Martin in "Dirty Rotten Scoundrels." That worked well enough until I could get it into a ponytail.
