If you need a label, try human.
I didn't develop a sex drive until I was 17 or 18, so I had a period where I thought I might be gay, since everyone around me had been "turned on" since they were like 11. But I didn't think of men in a sexual way either, so I decided that must not be it and I would just wait and see. Sure enough, I turned into the sexual tyrannosaurus we all know and love.
So, I guess my advice is chill the fuck out and stop trying to label yourself. I think "nailing the next whore you come across" would be dumb to do if you are doing it to reassure yourself of something. However, if you are just into nailing whores, I guess that is what they are for.
