Given guys' concerns about #metoo and being unwelcome, here are a couple tips that will improve your experience and hers:

  1. Hold her hand first. This will tell you whether she wants to be kissed, whether she wants to escalate, etc... and a woman will not generally upset, offended, and taking to the social media waves that you tried to hold her hand when she wasn't interested.

  2. I've by now racked up a few stories between myself and others of guys who ask girls out, the girls decline (or ask to just have a "friend date"), and then 2 weeks later, reciprocate and ask the guy out. Sometimes when you ask her out, she honestly hadn't considered it and needs a low pressure time period to think it through. If you can show that you are perfectly fine with the rejection, won't be petty and entitled about being turned down, that can often be enough to win her over. Showing the maturity to take a rejection can ironically be your key to success. There's a lot of advice here about not showing your interest, but I think it's fine if it's not needy interest.
