Dear Welcome to HCM We understand your concerns I went through your details. Sperm comes out without any sexual activity. Such a process is not abnormal or unhealthy. Body produces sperm cells whenever you are sexually excited. The produced sperm cells are stored inside your body. Because it is a waste product, body needs to throw it out. Body naturally throws out the waste product through urine or through nocturnal emission (dream / night fall). There is nothing to worry about it. You do not have this knowledge and because of that, you are anxious and worries about sexual / physical health. Such an anxiety is causing you premature ejaculation (PE). I suggest you should consult a psychologist for counseling. If you require more of my help in this aspect, please use this URL. http://goo.gl/aYW2pR.
