Is it worth it to try to fuck a girl past the first meet up or 2 if she’s fucked another guy on the first meet up?

I’ve seen this girl twice (both times heavy making out) but she’s stopped my attempts at escalating every time. Every time we do it she’s really into it, even making the first move and keeps going at it while I try to pull away. She calls me good looking and asks me how many girls I’m seeing.

I wouldn’t mind attempting once, maybe 2 more times before not doing anything else, but I heard through a friend that he fucked her the first time they went out. Not sure if logistics was the issue or not cause we would be in my car at night at the park so unless she’s really nervous about it being public I’m not sure what to think here. Wasting my time?
