Dear Welcome to HCM We understand your concerns I went through your description. I suggest you not to worry much. The white slimy liquid you are mentioning should be sperm itself mixed with urine. Sperm will be released by body in this manner if it is not been evacuated through natural means because it is a waste product. Premature ejaculation is either physiological or psychological. As you took many medication, medical reasons could possibly be ruled out. Means the reason is psychological. Anxiety about sex. You might need sexological counseling. I can help you through telephone. Contact me through customer care at www.healthcaremagic.com. Hope this answers your query. Available for further clarifications. Good luck.
