Singleness, the "Gift of Celibacy" and Healthy Complementarianism

What does it mean to have the gift of celibacy (or singleness)? Does it mean that you don’t desire sex or marriage? Or that you’ve been given an extra booster shot of the Holy Spirit that gives you radical immunity to sexual temptation (or at least prevents you from serious spiriutal hospitalization)? What actually was Paul talking about when he said that “it’s better to marry than to burn?” (1 Cor 7:7-8).
