Yeah we hunt for goodies on sale. You don't have a clue how much the thrill is in the hunt.
As for the paltry number of male groupies, I found this interesting tidbit from a 2011 salon.com article that makes perfect sense to me (along with your more warped, but equally valid theory): 'Male fans...are less likely to get past security, for very compelling reasons of safety. A girl is simply less of a perceived threat. The opportunity for a casual hookup to go badly, the potential consequences for a woman, are different and much more serious than they are for a man.'

Security, plus male insecurity about approaching powerful women on stage, equals far fewer male (vs. female) groupies. Women rock stars get stuck with roadies and vibrators, that ultimately may have a lot more staying power.
