Asparagus

I just went "number 1" after having had asparagus for dinner. I had other things to eat too, of course, but it's the asparagus that I need to address. Why does my "number 1" smell like asparagus one and a half hours after eating? In fact, sometimes the first morning "number 1" will smell like asparagus. Is this too much information (TMI)? Too bad. I need to know. This does not happen to me with any other food. Why asparagus? Why? Does this happen to others? With other foods, or just asparagus? Too many questions? Tough, I need to know. Thanks in advance.
