Brass Ovaries, similar to a male having brass balls. I female that is a tough negotiator or one that will not back down or compromise their principals.
The female genitals become engorged with blood during heightenedsexual arousal. An orgasm quickly dissipates the increased volume and blood flow to the genitals. Without an orgasm, it takes longer for this to occur.
Steel ovaries....the condition in which a woman is not afraid to hold her own and stand her ground. If man should find a woman like that, hold on to and never never ever piss her off or she will rip your balls off and place them in a tic tac container.
