Dear Welcome to HCM We understand your concerns I went through your details. The reason for your night fall (Nocturnal Emission) is lack of means to expel accumulated sperm cells inside your body. Whenever you are sexually aroused, sperm cells are produced and stored inside your body. That is a waste product for your body. If you do not masturbate of engage in sexual activities, body finds its own way to ejaculate the stored waste. The usual means are through night fall or through urine. Therefore, don t be anxious. The thickness of semen depends on many factors like what you eat, your water intake, stress level, how many times you ejaculate etc. You don t have to worry in that aspect. Because of the above given anxiety, you are now troubled with premature ejaculation. You need psychological counseling.
