A demisexual person does have circumstances under which they do experience sexual attraction. A person who doesn’t experience sexual attraction, regardless of how much they enjoy sex, is still asexual. The creator of this blog (me) is an asexual person who enjoys several kinds of sexual activity. Sex repulsion is not inherent to asexuality, and a person who experiences any frequency of sexual attraction can be sex-repulsed.
what would you say about someone who doesn't experience sexual attraction (based on looks/personality/whatever), but enjoys having sex and isn't repulsed by it? would that person be demi or ace?
