Can i be Omnisexual AND Demisexual?

I've always identified as Omnisexual, but I never really liked anyone unless I was close with them. I didn't know what Demisexuality was at the time, but I've recently learned about it. I know that I'm Omnisexual, and now I'm pretty sure that I'm also Demisexual. I'm just not sure if you can be both at the same time. I mean, it's not like anyone's stopping me, but I'd like to know if this is a thing.
