I'd be interested to see the orientation numbers broken down by sex/gender.

Using the "Sex" (not gender) and "Sexuality" columns, omitting blanks, asexuals, and others:

Male Heterosexual: 999
Male Bisexual: 142
Male Homosexual: 40
Female Heterosexual: 79
Female Bisexual: 62
Female Homosexual: 6

So the male/female ratio by sexuality is:

Heterosexual: 12.6
Bisexual: 2.3
Homosexual: 6.7

The sexuality percentage by sex is:

Male: 84.6% / 12.0% / 3.4%
Female: 53.7% / 42.2% / 4.1%

So while female bisexuality is almost as common as female heterosexuality here, the total bisexual ratio resembles the male bisexual ratio closely, as you would expect from the male/female ratio being so high overall (8 men per woman in this restricted sample).
