I've (26m) been on 3 dates with a girl (22f). First date we just played pool like friends, second we went hiking and I gave her a quick hug at the end. The third time we met we got drinks and our legs accidentally touched and she pulled it away quickly and she kind of ran off at the end saying she was "tired" but imo she seemed more like she was nervous or had to shit bad. Adter that I thought I ruined it but she texted me later saying that she really likes spending time with me and apologized for her "low energy" so I think I'm good still but I know I need to escalate soon. I just don't know how to touch her without it seeming awkward and forced. Plz help, what can I do? Thank you all.
