A recent research group looking into socio-sexual proclivities have discovered that straight males are alleged to be the most common group. They say 'alleged' as it appears there may be some undecided or those that wish to keep this to themselves.
Next on the chart is heterosexual women, closely followed by gay men, up 31% on the total four years ago.
At the bottom of the scale is gay dads, gay granddads and fully lesbian grandmothers occupying the second from the bottom position.
The rarest group of all being Bi-curious or Bi-sexual grandmothers, the research team were unable to track down a single incident of Bi-sexuality amongst groups of women who have had offspring and whose offspring have also had children, although due to the amount of Bi-sexual mothers that were found, it was concluded that it is only a matter of time until one of the bi-sexual mothers children, have children of their own.
Maybe not today, maybe not tomorrow, but one day, there will be Bi-sexual grandmothers, but for the moment, we have no Bi-Nanas today.
