Did this university not do research on wealthier women and their nature of sexual gratification? If it did they may perhaps come to a different conclusion(something like, not-so-wealthy men give better orgasms). This study is incomplete and i speak out of experience. I am not a wealthy guy(middle class suits me fine) but I have dated wealthy women(i have been pure lucky)and have been complimented for my exploits. This maybe irrelevant to the discussion but in my humble opinion the university should increase the sample size and make their study a little more comprehensive.
