Puberty and masturbation?

im 13 turning 14 in november, i have numerous black pubes around the base of my penis and some starting to go up and to the sides too. When i masturbate i ejaculate clear fluid and it shoots a few small drops. I also have very small black armpit hairs. How far am i through puberty and how long do you think it will be until i am almost through it and i will fully ejaculate white semen.
