I am sure you will all be shocked by this but the new areas of knowledge being opened by science are apparently never ending. Here it is, females apparently have orgasms! I know; I was completely bowled over by this newfound fact as well. Even more interesting is that their ability to achieve this "female orgasm" is partially based on genetics. So, if for some reason your partner is not achieving this thing recently coined "female orgasm" it is undoubtedly due to their genetic makeup rather than your own poor performance.
Science is wonderful because it not only opens us up to these amazing discoveries but also provides convenient rationalizations for men (Who, by numbers, dominate science) who just can't seem to please their partners.
A few interesting tidbits from the study:
14% of women achieve orgasm every time.
98% of men achieve orgasm every time.
32% of women report never, or almost never, achieving orgasm during sexual intercourse.
99.9% of all male scientists think both the female orgasm and foreplay are myths.
Ok, I made that last one up but I wouldn't be surprised if it was in the upper 80's.
