Men (and women) who are clueless to the powers of the clit-thus mostly ignoring it altogether.
Jane: was he good in bed? Did you cum?
Jill: cum? I wish! He's clit clueless. He somehow really thinks I'm cumming JUST BECAUSE he's fucking me. Damn it! Clit clueless! And I'm too old to be teaching men about clits. That's why I have a vibrator.
