Homosexuality is a characteristic of those who are physically, emotionally and spiritually attracted to other people of the same sex. That is, for you to become homosexual you need to be attracted to people of your gender, it does not depend on whether your friends are gay or not, it just depends on your interest in romantic and sexual partners. In other words, spending time with a homosexual person will not make you identify as homosexual, so you will need to be attracted to a same-sex person.
