OP has not once, put forth any logical, intellectual, philosophical or scientific argument or basis that correlates individual human superiority, spiritually, enlightenment and/or evolution to asexuality/abstinence.

OP claims a satisfactory marital and interpersonal experience and relationship, based on a mutual state of emotional connection and agreement with another human. Fine, that claim is legitimate. However, OP has not articulated any thesis or proof to validate claims of a general or specific higher state of mental or emotional being, based on abstinence or an asexual relationship in humans.

OP's marital state and relationship is valid, however, OP's claim, as submitted, of any individual or collective differences in humans due to sexual abstinence or an asexual relationship is a FAIL.
