Dear Welcome to HCM We understand your concerns I went through your description. I suggest you not to worry too much. Night fall is normal. Body produces semen whenever it is sexually aroused. That semen is collected and discharged at appropriate time through masturbation or during intercourse etc. Otherwise, it is discharged through night fall. Don t be alarmed of it. You might need psychological counseling., I am more than happy to provide telephone psychological counseling through healthcaremagic. Contact me through customer care, www.healthcaremagic.com. Hope this answers your query. Available for further clarifications. Good luck.
