Pope discusses sex

Pope Benedict XVI's first encyclical, expected in the next few days, warns believers not to confuse love with lust or degrade it "to mere sex".

	It is Pope Benedict's first encyclical

The encyclical, a papal letter to bishops that sets out Roman Catholic policy, discusses the relationship between "eros", or erotic love, and "agape", a Greek word referring to unconditional, spiritual and selfless love.

"It is not totally negative on eros," a Vatican source said. "It argues that eros under the right circumstances is OK."
