I need a completely new hairstyle to replace my mop :o) [Male, 16 years old]

[Mop Cop]

Hi everybody
My names David, and I joined this forum because I'm looking for a new hairstyle that would suit ME best, but I want a change. And also because... well... my hair at the moment sucks.

I have really thick, wavy hair, that has a bit of poof. Normally, I straighten it a bit, do that it's less wavy and flatter, so my poof problem goes byebye, but sometimes, when I do not straighten it, I have to wear a hat to bring it down a bit . When I straighten it, it doesn't look too bad, but it's not very flattering anyway. But yes, the vast majority of days, I straighten my hair a bit.

I'm looking for a different hairstyle, rather than just "get a trim, just cut off a few inches, put in some layers, tone it down a little". I'm ready for a change, although I'm FREAKING scared of the results. I'm quite the metro. I must say. I really do want change though.

If you think long hair would suit me best, please tell me, but I'm really looking for a different style. I kind of want a medium length, that I would probably have to straighten, which I have no problem with. I'm open to ANY suggestions, but I'm more musical, and not very sporty, so I'd rather not have spiky gelled hair with blond streaks and a diamond earing.

Thank you

Edit: Here are some pictures.

Straightened a bit, sorry for the serious face, I couldn't find an angle to compliment my smile:


Unstraightened, after hat... This pic doesn't look much like me though:


Finally, here's a pic where I full out look like a woman:
