Gays sexual orientation
It happens due to the hormonal changes of puberty. Thinking sexually about both the same sex and the opposite sex is quite common as teens sort through their emerging sexual feelings. They may be concerned or worried about whether their son or daughter will be bullied, mistreated, or marginalized. But in addition, gay and lesbian teens often deal with an extra layer of stress — like whether they have to hide who they are, whether they will be harassed about being gay, or whether they will face stereotypes or judgments if they are honest about who they are. No one fully understands exactly what determines a person's sexual orientation, but it is likely explained by a variety of biological and genetic factors. They might feel they need to deny who they are or hide an important part of themselves. For most people, coming out takes courage. They feel comfortable and secure about being attracted to people of the same gender.
