Just want to say thanks for the fact you inculded Asexuality in the options, because it is very rare to find in surveys, and the option of 'other please specify'. I would say to include Pansexual, and I think there's ones called Polysexual, Demisexual, Gray-A, but I guess they can use the 'other please specify'.
So thanks for that.
Also for including an 'other' option during the choose sex part, that's really nice.
So yeah, I doubt anyone will find this offensive since you kinda covered everything nicely ^-^
