This is what depresses me so much about the idea of dating. Like it's a game to be played, with rules, that you jump through these hoops in order to get your reward. No wonder I never get laid.
If you're lucky enough to find somebody who likes you and wants to hang with you, whom you like and whom you want to hang with, then great. If you find each other physically appealing then so much the better. Do whatever you want, go wherever you want. If you fuck on your first meeting why should anybody give a shit? If you're really into each other why should you not fuck at the first opportunity?
Really. If you find somebody you're having fun with just do whatever you want together.
