I asked ~30k women if they were on birth control or not, plus a ton of other questions. I'm looking at the findings and there's some fascinating stuff. To start, here's the % of women on birth control, sorted by their gay-straight preference

Here's the % of women who reported being on birth control, sorted out by age. I have lower sample size for older people so this only shows <40

I asked women "how hot are you compared to others"? Here's women separated out by how they answered. You can see there's a slight increase the hotter someone thinks they are. (this one is filtered to women aged 20-25)

And here's the % of women on birth control split out by their relationship status (ages 20-30)

These are interesting, but the *really* interesting stuff is in sexuality and attraction. I tested a ton of stuff - attraction to masculine vs feminine people, mental illnesses/anxiety/depression levels, general horniness, interest in rougher vs gentler sex.
