I'd suggest that the questions on sex, gender, and orientation be re-factored. One schema I've seen that may be worth starting with runs:

• Gender role: masculine, feminine, non-binary
• Gender identity: man, woman, non-binary, agender
• Romantic orientation: heteroromantic, homoromantic, biromantic, aromantic...
• Sexual orientation: heterosexual, homosexual, bisexual, asexual...
• Sexual behaviour: heterosexual, homosexual, bisexual, celibate...
• Sex: male, female, intersex
