I am so sorry but...I need help on seeing if I am doing things right. I jerk off 3 to 4 times a day and I spurt out white stuff and it has a smell. I am 13 and my dick is only 4.5 inches long. And my dick also just goes erect out of nowhere. Also, I need to know if others jerk as much too!!!! All answers are welcome.
The white stuff you're seeing is likely ejaculate (or pre-ejaculate if it happens early on while you're masturbating). As for the surprise erections, that's pretty common for someone who is hitting puberty. You can read about why they happen here: Not Everything You Wanted To Know About Puberty (But Pretty Darn Close)
From my understanding, as long as masturbating doesn't get in the way of other things you need/want to do (i.e. school) then you can do it as often as you like.
