I have been asking women to explain how they achieve orgasm with a lover for years. Very few women ever respond. In fact, probably more men have to say about female orgasm than any woman does. But even men cannot explain how women achieve arousal. So how do men think women achieve orgasm if they are never aroused. The fact that female orgasm is a topic for discussion is clear evidence of the mystery surrounding it. No one discusses male orgasm because it occurs reliably. Men can explain what arouses them. I am challenging porno orgasms - those we see women apparently having in pornography. I have found not one single woman who can explain how such orgasms might be achieved. In particular they have no concept of what arousal is. They associate it with emotional feelings within a loving relationship. But orgasm is a response of the brain to erotic stimuli. It has nothing to do with a relationship. Men should know this but they are so intent on proving that women are pleasured through intercourse that they forget common sense and logic. No arousal = no orgasm.
