look up any word, like ethered:
Flash erection.

An erection lasting a few micro-seconds. This is invisible to anyone but the trained eye. It is an involuntary muscle reflex.

Not to be confused with a "stirring in the loins" - a more labored and deliberate feeling, involving a certain degree of participation from the subject.
