Beware of the big fat simile in that post. A personal impression does not an offense make.
The offense of "sexual assault" requires "sexual behavior" to take place. A security pat down delivered in the appropriate, formal manner is not a display of sexual behavior though it could become such. The mere touching of "intimate" areas does not make it "sexual" per se, however.
And nor does voting this down change the letter of the law. Think about it for a minute. If any unauthorized touching of one's genitalia is "sexual assault", a surgeon performing an emergency operation could be in serious trouble. Thankfully the law in most nations distinguishes between sexual and non-sexual touching, even if the subject of the blog entry does not.
