I'd weigh in with affection, too: nobody ever died of celibacy; plenty of people have died of loneliness (at their own hands, if necessary).
And I disagree with JanH: when "the partner's imitating an inflatable," that's sex without good manners or interest, not without affection. Or sex with fear, sex with embarrassment, you get the idea. You can be courteous, kind, and have a wonderful time with sex, with someone you've only known for a few minutes, or only know by sight.
But this is a false dichotomy, anyway. In real life, one often leads to the other. Life is untidy that way, thank the Powers.
And I recall an instructive story from the life of Victor Anderson: In a vision, he was once ordered to choose between love and magical power. "If you seek power, you will never have a lasting love relationship for the rest of your life."
Victor's reply: "Get thee behind me, evil spirit." He reasoned that no one who would make him give up love could have anything else he wanted...
Well, it seemed relevant to me when I thought of it :)
