So apparently she started an argument over some stupid shit, and turned around and told him; you're nothing, I'm a woman and I can easily find another cock. I told him you should have told her, I can easily find a cock too. That's not something to brag about. My friend couldn't stop laughing.

Female and male sexuality are not only not the same, they cannot be compared. Any comparison is worse than comparing apples to oranges. It's more akin to comparing guy giving girl money vs girl receiving money from a guy. Related but totally different actions.
