Sex Positive: I don’t feel sexual attraction but I do enjoy the physical sensation of sex. (Maybe even crave it!)
Sex Neutral: I can have sex but I don’t need it. To be honest I have no strong feelings about sex. But a slice of pizza would be better.
Sex Repulsed: I don’t like sex. I don’t want to have sex. I’m not going to have sex with you. I understand that people enjoy sex but I do not.
The presence of a libido does not invalidate any of these orientations. Dicks jokes and sexual humor do not invalidate these asexuals. These orientations are a SPECTRUM and are very fluid. Asexuals can and do exist in between theses definitions.
