Topics like sexual orientation and gender identity are considered taboos in our society. However, conversations about these things are not bad or immoral. Always be open to listening, learning and understanding more about sexuality and gender identity. Be it from conversations with others, reading or via the internet.
The more you learn, the better you will understand yourself and people around you. You will begin to feel empowered to be who you are, and to be a better friend and ally to others.
