Relax there's nothing wrong with u.......that fluid is normal if u r a healthy male.........n where did u get the notion that it has calcium. It is normal lubricantion liquid which all healthy males produce n whenever there is pressure like urinating n defecating it comes out..........if it becomes itchy or extremely bad smelling than it is a problem as it indicates infection. In your case enjoy the fact that u r a healthy male. Cheers
