What does he mean by this statement?

There’s a guy I know who’s chased me online and in person for a year. I asked what his motives were, if he wanted straight sex or a romantic relationship and he said preferably sex but we could be romantic if we had to be. What does this mean? I have Asperger’s and I don’t pick up on social cues.

I know he’s hitting on me but for what? Was he making and jokes or being direct? That’s not clear to me when it’s online.
