With the results the researchers additionally expressed that “Women preferring deeper penile–vaginal stimulation is additional seemingly to possess vaginal orgasm, in step with vaginal orgasm evolving as a part of a feminine mate selection system affirming somewhat larger than average penises.”(Miguel, Miller & Brody 2012:3079) For this reason penis size is very important for ladies as a extended penis is related to bigger vaginal sexual climax that is consistent.Another evolutionary theory from the article “A Typological Approach to Testing the evolutionary Functions of Human female Orgasm” by (Belsky & King 2011) approaches the question on ‘why females have climax/orgasm’? some researchers states that female orgasm frankly carved by natural process to extend reproductive and generative fitness by the distribution of genetic materials in the generations ahead to come …show more content…
in the article “Implications for “Female Orgasmic Disorder and evolutionary Theories of Organism” by (Zietsch & Brendan 2011) a research was conducted to check hypothesized evolutionary functions of the female orgasm. within the analysis Zietsch and Brendon examined correlations in a community sample of 2,914 adult female twins from Australia, who reported their climax rates throughout copulation, masturbation and alternative sexual activities, and made them complete a personality, and gender questionnaires. They discovered that feminine orgasmic disorder assume that lower rates of orgasm are not functional, which means that having high rates of orgasm are useful/functional. The results of the study was that although sexual climax rates showed high variance across ladies, they were mostly phenotypically and genetically not dependent of alternative
