Context: First date - met on okcupid.

I invited her over to my place for a smoke and to watch TV after we got drinks at a bar nearby. Her response "Are you trying to fuck me?" with a grin on her face. My response grinning: "If you want me to fuck you, I'll fuck you". This got her over to my place, and it got hot and heavy, but I didn't f-close (chock it up to first date...or something).

Anyway, I think my reaction was decent. I wasn't phased and she was definitely shit-testing me. Any advice on what a better response would have been?

Thanks seddit :)
