As a submissive i would without question be thinking WARNING! After a day you can be full of ideals but it is not safe to follow up on those. How much can you truly know about someone in that short amount of time. Your safety should be his priority and if you raise a concern he should without any question take his foot off and if he doesn't you need to back away. It is nice to get the attention and flattering to think in such a short space of time you have made such a wonderful impression. If he is that keen he will be happy to wait and learn more about you and support a much more realistic and safe meeting in the future when it is right for you. Good luck and good for you for asking for advice!
