Condemning homosexuality as sex outside marriage is unfair, since it is the Christian church which does not offer the right of marriage to gays and lesbians. If it were to do so, they could enjoy sex within loving relationships, sanctified by the Church, just as heterosexuals do. Jesus’ main teaching was clear - "love your God and love your neighbour" - and there is clear difference between adultery and homosexuality in this respect; the former causes pain and has a victim (the betrayed partner), the latter can be a purely loving relationship.
