You NEED to see a doctor, preferably a urologist, about your testicles - NOW. Your description of a "ball of string" CAN indicate a variocele. It's basically a big vein. The problem is that it can raise the temperature of your testicles and that can lower your sperm count. You DO want this treated sooner rather than later.
Not all guys can ejaculate via "traditional" up and down methods. Some guys need to "hump" things. You'll find a way. That you have "wet dreams" is very NORMAL and a sign you are physically and sexually mature.
Do see a doctor - soon.
