Re: Why do people ask us?
To answer your question,
People are fragile creatures. We need to have people there to support us. I do agree with you when you say that figuring out one's sexual orientation is a personal discovery...but sometimes humans look to others for support on their quest to discover self-truths. In essence, people ask you this because of a mental insecurity. So, the best thing for you to do when someone asks you this is be supportive and help them to find their truth.

"Trust in the Lord with all your heart, and lean not on your own understanding; in all your ways acknowledge Him, and He shall direct your paths." (Proverbs 3:5-6)
Forever praise Him
