Newbies

So two weeks ago we (23f & 28m) started our open relationship, we first started with downloading tinder and getting back into the flirting game. He had someone willing to meet up but they ghosted him. I met someone as well, got cold feet and cancelled, well we’re trying again this week, the same person I’m meeting with Friday. My boyfriend doesn’t have anyone yet, he says he’s 100% okay with me going; and if he doesn’t find someone by then it’s not a problem. This’ll be my first hookup in over two years. Is it normal to feel nervous and scared? Am I not ready?
