Hello, fellow ace here! For some further clarifiction that not all asexuals fit into one neat little box, some aces DO experience sexual urges, some don't, and some are even sex repulsed. It really depends on the individual - the only real defining factor is not having a sexual attraction to other people.
That being said, you can still totally find a potential partner attractive in that you like the way they look, but that appearance doesn't make you want to jump 'em. If you get my drift.
