Depends on what you mean by chastity and whether you delineate a long term sexual relationship by an unmarried couple (common law marriage) from a series of one night encounters. Also, there is the question of whether sexual pleasure is an end in itself. If chastity means no oral sodomy or manual stimulation of a female partner to orgasm, whether full or partial, I will have no part in such chastity, which is neo-platonic with an asexual bias, with nothing to do with authentic Christianity. My point is that being celibate and chaste in clergy comes from either an escape from unwanted homosexuality (self-loathing) or natural asexualism, which like homosexuality, is an orientation in and of itself. Such an orientation has its own proclivities and ideals which have no empathy for what the rest us experience. It is not just-chosen or taught, it is hardwired. I don't want diagnostics hard wired for aloneness linked to my system, which is most certainly not wired that way.
