The Christian church has very definite views on love and sex which are based on passages from the Bible.
Love is a warm affection for, or a close attachment to, another person.
Sex is often used to mean sexual intercourse. Start here Christians are encouraged to love God and each other in a platonic , non-sexual way. Dear friends, let us love one another, for love comes from God. Everyone who loves has been born of God and knows God. Whoever does not love does not know God, because God is love.
