How would you translate "questioning" as in "questioning one's sexuality?"

Question

I'm translating a survey that asks about people's sexual orientation.

Answer 1

Hi:

The simplest way would be: ¿Cuál es su preferencia sexual?

When translation it's always better to translate the meaning rather than sticking to the words.

In some countries, the question would be illegal especially if asked by an employer.

Answer 2

I believe you can also say "¿Cuál es su orientación sexual?". Will probably depend on the audience taking the survey and the country where you conduct the survey on which phrase you should choose for maximum understanding. Good luck!
