Defined as unimportant, trivial etc. But this is all subjective and can be interpreted by different people in different ways. The events of Sep 11 01 were the culmination of a focus of hatred against other people by terrorist men. One of the things that should have been learned by the whole world from the events of that day should have been that goodwill towards men and women begins at grassroots level and practiced in your everyday life. So, caring about your woman (and man) having an orgasm is a little start at getting the positivity ball rolling in the world. Lots of little things add up to a big thing so to speak. This may sound like idealistic claptrap bollocks, but the sentiment is still sound.
Sorry you didn't have an orgasm darling, let's just have a nice cuddle. Insensitivity and selfishness is so September 10th.
