God loves you as you are.
You can be both a true Christian and a loving, sexually-active gay, lesbian or bisexual.
It is totally okay to be romantically or sexually attracted to someone of the same sex as yourself and to act on those attractions in a non-harmful way.
You can ignore those people who say that the Bible condemns homosexuality, because the relevant verses applied only to people in the ancient biblical cultures. They don’t apply to gays, lesbians or bisexuals today.
If you would like more info, see the Gay and Christian site.
Or have a look at A Gay Fairy Tale. Very interesting!
