When I ejaculate nothing comes out?

If you've been ejaculating a lot within a short period of time, it's probably nothing. It just means that you're "outta gas". If this is the case, wait a couple of days and you will see that everything has gone back to normal. If you are barely coming into puberty it could be that you're young enough that you just can't produce sperm yet. However, if you've never produced anything you may want to ask your doctor.
