For those who wish to amend their profiles, I have amended the interest choices. I've split Transgender into two parts

1. Transgender (MtF or FtM)

2. Transgender (Male to Eunuch)

Those who previously checked "Transgender" will now appear under option 1.

I've also added BIID Body Integrity Identity Disorder as an option.

I did get an error when I tried to change my profile.

A required field called My identity gender is is missing or has an invalid value.

The change worked for me and I am glad my profile more closely represents me.
