Gay men can have their sense of humor/irony/bitchy theatrical campy-ness, but lesbians really are humorless. Because with them it's all faked emotions --- fake horniness, fake attractions, fake humor. They are, for the most part, bitter unattractive women -- and -- big secret -- when they pair up they immediately stop having sex, because there'e nobody to pretend to anymore.
Totally unlike married couples...
Just kidding
