"People speak of "sexual morality," but that is a misleading expression. There is no special morality for sex. No matter what you do with yourself, whether you go to bed with girls or with boys, and no matter what it occurs to you to do with them or with yourself, no moral rule applies to that sphere of activity other than the principles that govern every aspect of life: honesty, courage, common humanity, consideration." - Jens Bjornboe
