When I ejaculated, a watery substance spurted out in droplets but there was also tinges of white in it. There were about 10 droplets that flew out of my penis about 10cm away. What stage in puberty am I because of this and is this normal for 14 year olds?
The clear liquid was pre-ejaculate fluid. The white probably indicates that you are starting to produce semen, but not in quantity yet. What you describe is not unusual for someone just starting to produce semen.
I cannot tell you what stage you are in because boys can start producing semen in either stage 2 or 4. You can use the Tanner State Calculator to estimate what stage you are in.
