its really hard to find an adult class for gymnastics... I tried. its catching on in some areas but still hard to find.
You may like crossfit and participating in the crossfit games. I am liking crossfit because its the same hard conditioning as gymnastics and making me look super sexy! Cant wait until im fit enough to compete at the games. The training is varied and really fun, you don't do the same thing every day.
I think gymnastics would be a good sport and you won't look like a boy! I have a gymnastics meet today and they are sooo fun! Since you're 16 you're in high school (most likely) so to could easily join the high school team. With my high school team you don't have to try out, you just pay an athletic fee. It might be different in your gym.
Good luck!(:
I think playing cricket or Batminton can be good game for you. These two games will be better for you.
Of course you can select Basketball but it will need much time to improve on this .
Any form of dancing. It will increase your cardiovascular system and leave you with a great body
