Good point. Our experience has been that generally the super aggressive males are more like gnats. A bit annoying, but usually they move along quickly, or can be moved along with just a little effort. The super aggressive females though, can make a straight girl's night a little hellish.
My observation about the difference between the aggressive male and female are:
The male is generally a goofball/dumbass that hasn't figured out protocol in a swinging environment (and may never figure it out).
The female is generally drunk.
