not find her attractive (enough). Another reason could be that he wanted to end the sex, but held to the idea that sex isn't finished until the man has orgasmed, and so he therefore pretended that it had happened. It could also be that the man actually didn't want to have sex to start with, but he felt obligated to have sex when his partner asked for it because of the myth that men always want sex, and he didn't want to appear 'unmanly'. For men, it's more difficult to fake an orgasm, since ejaculation usually accompanies orgasm in males, and their partners can usually see that happening or not. Faking orgasms in men becomes easier while using condoms. In rare cases, a man is worried that the condom is torn or will tear, and that he will unintentionally make his partner pregnant, and so he fakes an orgasm in order to avoid ejaculation. Brain activity In a 2005 University of Groningen study conducted by Gert Holstege and Janniko R. Georgiadis, the brain activity of 24 men and women (12 couples) was observed in an MRI scanner in different circumstances. For the female participants, their brain was scanned in four states: simply resting, faking an orgasm, having their clitoris stimulated by their male partner's fingers, and clitoral stimulation to the point of orgasm. Brain scans found that, when women were tasked to fake an orgasm, the female brain centres that control conscious movement remained active, whereas when they experienced real orgasms, all activity disappeared from the movement control centres, and the light from the emotional centres of the brain went out as well. With the exception of some Brodmann areas of the cerebral cortex (which only showed activation in men), the same brain regions were activated or shut down in men and women during real orgasms (although the female orgasm was found to be longer and more intense on average). According to a PET study by Huynh et al. (2013) the dorsolateral (left) side of the pontine tegmentum area was always activated whenever women had a real orgasm, attempted but failed to have an orgasm, and imitated (faked) an orgasm, whereas the ventrolateral (right) side of the pontine tegmentum was only activated when women had a real orgasm. Other factors Orgasm is not always achieved easily during sexual activity. For both sexes, the condition of being unable to orgasm during
