I'm personally embarrassed by the presence of "fine women" if they've been paid just to show up - it makes tech guys look like the only time they get to talk to a woman is if she's being compensated for it.
I think that underscores an insecurity about your ability to interact with attractive women. Strippers, exotic dancers, and eye candy in general have and will remain a big part of male-only events. You can whine that there should be more females and that is fine. If there were, and they cared, they would voice out against it. This is not uncommon.
