Should Parents, families and friends talk to a loved one about his or her sexual orientation or gender identity before the person talks to them? 

It’s seldom appropriate to ask a person, “Are you gay? Your perception of another person’s sexual orientation (gay or straight) or gender identity (male or female) is not necessarily what it appears.
No one can know for sure unless the person has actually declared that they are gay, straight, bisexual, or transgender. We recommend creating a safe space by showing your support of LGBT issues on a non-personal level. For example, take an interest in openly discussing and learning about topics such as same-sex marriage or LGBT rights in the workplace, health services and social groups. Learn about LGBT communities and culture. Come out as an ally, regardless of if your friend or loved one is LGBT.
