What you described seems perfectly normal. The consistency of your ejaculate will differ depending on your diet, exercise, medication taken, mood, etc, so don't worry how it looks, just as long as there is no blood or anything then it is fine.
As for shooting your load off, it depends on how sexually aroused you are, the greater the arousal and play time, the further it will shoot and the more *** you will produce. Most of the time the *** will just flow out of the tip of the penis.
It normally takes about 6 hours for the sperm to be replenished so the more you orgasm in shorter period of time the less ejaculate you will have. I remember once when I was jackin off a couple of times every hour for most of the day, I eventually was orgasming with hardly any ejaculate coming out. So don't worry about anything, just enjoy the cums and concentrate on the quality of your orgasm and not the quantity of your load.
You didn't say how old you are, but the prostate works best with regular ejaculation. If it doesn't go back to normal by ejaculating once or twice a week for a couple of weeks, a urologist could check this out for you. You would probably have to ejaculate into a cup in the bathroom, and your prostate would be palpated to see if it is normal size. They wouldn't be checking for cancer as much as enlargement and I think maybe infection. I haven't worked for a urologist in a while, but a checkup like this should be no big deal for a urology office.
