I have noticed the same thing and would like to know what this is all about. Is it an std or normal or what?

The doctor said it was a case of an inflamed prostate caused by a prostate infection (prostatitis). The enlarged prostate is close to your poo poo muscles, so when you poop it puts pressure on it. The prostate is also next to your seminal vesicles, which is why that stuff is noticed ( a mix between seminal fluid and other stuff). He said it is not uncommon and that a 2 wk cycle of antibiotics would take care of it.
