At that time. whenever I get close to the one I love, it will
automatically hardens... 
But it never happened again after she and I broke up. Well, what I
meant is, going out with other females alone never produced such an
autonomic reaction, even if I regularly go out with the
female...
Couldn't quite find back the feelings. I think they were gone the
day she left me... 
And, I dun normally get hard ons in the train, or almost
anywhere...
Sigh, am I using the female as a substitute for my ex?
