Well they say attraction is there actually pretty quick most of the time. It’s either there or it isn’t. It doesn’t mean you must proceed with physical actions.

Usually if you feel strong attraction, you ask if they like to see you again. Even the most adventurous woman will be apprehensive re sex after 2 hours but they might be up to kissing or what not. Nothing wrong with casual if both parties are up to it. But even with casual you might not want to suggest intimacy after 2 hours. No harm in meeting again
