I am 18 years old and whenever I wake up in morning and if I again go to bed for little sleep then suddenly my body starts jamming i.e. I can't control any movement of my body it's get blocked and body jammed and then I got a feeling (that we get when we do masturbation and at a point where we know if we do more then sperm can come out that feeling) and after few seconds my sperm comes out and my body starts working i.e. I can control it's movement, I am suffering from this problem from 5-6 months and also sometimes at night while sleeping also sperm comes out and I have stopped doing masturbation but still every month at night it comes out and now due to this morning problem every week it happens, this month it's happened 3 times.
