If I don't cum for a while -- for whatever reason -- I will occasionally notice after I urinate there's what appears to be some cum produced when I shake, after contracting the muscle. Physiologically, I'm not certain if this would be an overflow of cum or precum. I know it's not piss because of the appearance when it hits the toilet bowl or bottom of the urinal. It only happens when I haven't cum in a few days or longer. Obvious solution is to shoot a load, but I'm wondering if other guys experience anything similar? Thanks.
