Dear Welcome to HCM We understand your concerns I went through your description. I suggest you not to worry much. Body produces sperm cells whenever it is sexually aroused. Produced semen should be thrown out of the body. Sexual intercourse, masturbation helps here. If you do not indulge in such activities, body finds its ways to throw out the semen and one method is night fall of drips while urination. These procedures are normal and cannot cause physical weakness. Body weakness, premature gray hair etc are not at all related with night fall and dripping of semen. But anxiety is the cause in your case. You might need psychotherapy and other cognitive behavioral therapies. I can help you through telephone. Please do contact me through customer care of www.healthcaremagic.com for a telephonic consultation session. Hope this answers your query. Available for further clarifications. Good luck.
