I can't stop thinking that the necessity to define your...I still don't know, if Bible means 'sex' or 'gender'?.. comes from Abrahamic religions where it's written in the scriptures that a person should not have homosexual sex (punishable by death) and not even wear the cloth style of the opposite sex (punishable).
And it's important in the cultures based on Old and New Testament.
But if one lives in a society based on a different religious system (like East Asian cultures) or atheistic (like many countries in Europe who have dominating Christian churches, Jewish communities, and large Muslim diaspora but in everyday life tend to take scriptures as fiction rather than instructions for real life), it doesn't have that much importance.
Dress as you like and love whom you like, it's your personal space and you have right not to reveal it to outsiders. And the outsiders have no right to inquire further if you tell them 'it's personal hence not your business'.
But it's impossible to make personal things personal in a society which believes that it's necessary to stand in front of a crowd (because it's not a crowd anymore but your church where actual strangers are your 'brothers and sisters') and tell them intimate things that you'd rather keep to yourself. Because if you don't they get aggressively suspicious about you.
