<s>[INST] While urinating today i seemed to ejaculate towards the end.  I was not sexually aroused at all and hadn't been erect since i woke up which was 6 hours earlier.  I am 39 and don't ever remember this happening.  What could cause this or what does it mean? [/INST] Dear, We understand your concernsI went through your details. The cloudy liquid came out after your urination is indeed semen. But there is nothing to worry. Semen is always available within your body and body removes through such ejaculation methods. Nocturnal emission is also one among such ejaculation methods. This is body's natural process.If you require more of my help in this aspect, please use this URL.
