Sex and Companionship

Most men wouldn't think at the end of life: 'I'm glad that my wife and I had such great sex.' Wouldn't they be more likely to say: 'I'm glad I had such a good friend and companion'?

If its true, I wonder how this insight affects the question below. Perhaps a deeper human need than sex is friendship and companionship.

Singleness and Sexuality?

Here's a question from a good friend of mine.

If desire for one’s husband/wife is a good gift from God, but lust is sinful (and in danger of sending us to hell), how can single people express their sexuality and desires in a Godly manner?

Any ideas? (beyond get married - they really want to)
