No, it's just annoying or a simple threat if it's one time only. From http://www.merriam-webster.com/dictionary/harass (emphasis mine):
> Simple Definition of harass: to annoy or bother (someone) in a constant or repeated way; to make repeated attacks against (an enemy).

"sexual harassment" is a term with its own specific definition, which is not precisely a naïve combination of the simplest common definitions of "sexual" and "harassment".
Pretty sure there are a LOT of women who would strongly disagree.
