Women, while fun to have around, are practically invisible at a gay party. Everyone is catering to open the velvet ropes between a woman's thighs. That's because if there were no women, men wouldn't spend money to get them fucked up and try to sleep with them. Women are used to being let into clubs first, not having to pay a cover, served at the bar quickly, and basically allowed to do whatever the hell they want to do in straight bars.
This is the most important lesson for all ladies to know before they step foot in a queer establishment (unless, of course, it is the fabled lesbian bar).
