I've been squirting a few months now and have come to know my cum. It smells like me (but different) and after the wet spot dries, leaves no stain even on my white-ish sheets. However, the last time, my ejaculate obviously had a higher urine content than normal as it did stain and left an unpleasant scent. This wouldn't be an issue if I hadn't forgotten to throw down a towel then so it affected my bed/sheets. If I am using a towel, I don't really care if it is urine but I was wondering if anyone else had times when their ejaculate had a higher urine content than usual and, if so, any ideas as to why?
