research shows there is no gender split; men and women are equally likely to be asexual. However, asexual men
are much more likely to masturbate
than asexual women; as likely, it would seem, as men with "normal" sex drives
, suggesting that they are responding to a physical imperative. When Brotto conducted an experiment to measure the vaginal reactions of female participants to visual sexual stimulus, the physical reactions among asexual women were the same as that of women who report an otherwise "normal" sex drive
. Brotto also says there is nothing to suggest that asexual people are any more or less likely to have suffered childhood abuse than anyone else.
