I don't think you are asexual. I think it's incorrect to consider sleeping with someone - that is, penetrative sex - the primary criterion of a "sexual relationship" since there's 'less' you can do that still falls well within the purview of sexuality. I'm not sure why the Cambridge definition said "sexual relationships"; really it should be "sexual activity".Riku said:Just to be clear, i'm heterosexual, but I'm also asexual which means that I like women, I can find them attractive, both in personality and in physical form but I do not want to sleep with any woman.
While it's undoubtedly true that not all (or even most) attraction is sexual (and I admit it's impossible to draw a hard-and-fast line between the two) "physical" attraction as you put it sounds contrary to asexuality to me, depending on what you (don't) have desire to do. I suppose one could be able only to love one gender as a husband/wife but not be sexually attracted to them and thus be 'hetero-asexual', or both and be 'bi-asexual'.
Interested to hear you thoughts.
