I fucked up badly recently. First date (I've only known her a few hours) and right before sex, she gets cold feet I guess and starts saying she has to work the next day and that she has to be a good girl. I was making out with her but she kept pulling away. I'm guessing I did the right thing by not forcing the issue?

And in the future, how would I know if she's just teasing me with the "nos" or she really doesn't want to have sex.

ps I'm new to the game, although I'm fairly old at this point
