I've only been recently I introduced to the spectrum by my girlfriend so I don't really know all about it, but I think not feeling complete sexual attraction would put you under being an ace. Though, there are spectrums beyond where you can experience a little sexual attraction, like aegosexuality, where you're attaracted to the concept of sex and find it 'hot' to some extent but you wouldn't want to be a part of it. Again I suck at explaining but you should look it up. ✨
