@ebel often allosexual is used for someone who doesn't experience asexuality, I've also seen zedsexual
@ebel if you are looking for words for people outside the asexual spectrum, those are allosexual and zedsexual (there are also a bunch of others but allo is more common).
If you are looking for a specific identity that means "I'm not asexual but I don't want to specify which gender(s) I'm attracted to", that would be comsexual.
Please also note:
1) There are asexual people who experience some sexual attraction (see: demisexual, fraysexual, graysexual, etc.);
2) Saying asexuality is not an orientation/a sexuality because of the lack of attraction has a lot of negative connotations attached to it (such as when people demand aces to disclose their "real orientations" since asexual is "just a modifier" for them), so I suggest avoiding it!
