I did ejaculate without touching my penis just about a day ago. It was to porn and it happened to me a bunch of times. At least you didn't make my mistake of relapsing (and it was after 130 days of no P or M!!!). :/
I wouldn't be pretty upset in your situation. Maybe it really is a sign that you are getting better and you should try to have sex with a girl? I hypothesize that you will have some problems with PE at this point because it seems you are very sensitive, but people report that this goes away with practice.
