For the first time in a long time, I came twice in one day.  In one evening, in fact.  Didn't pud out much; it's not like I can turn back the clocks on my ejaculate.  But both times I was out of my mind tired, and that meant that all my blood rushed into my dick, and that got me all horny, and so I looked at some porn on the Internet and started touching myself.  There might not have been semen, but there was completion, and thank goodness I can still get it up and get it out if the mood strikes me.
