Dwinsexual is an a-spec identity where one felt sexual attraction for most of their life but after a particularly strong/intense sexual moment/relationship all sexual attraction dwindles away and fades. There could be multiple reasons why the attraction faded; the sexual relationship was abusive and all sexual attraction faded for trauma related reasons, after this strong sexual relationship ended they feel like they could be with nobody else ever again because they thought they'd found the perfect person, or the extreme sexual moment/relationship simply made them uncomfortable and the sexual attraction dwindled. Dwinsexuals were born allosexual, but this does not make them any less on the asexual spectrum.
