My opinion:
Don't bring it up on next date. Don't have sex on next date.
After you've dated for about a month or two.. If you feel a strong connection, and still feel you both have lots in common. (That you are enjoying together in common, without having sex)... THEN, talk to her about it. Talk about wanting to put the breaks on & that you are sorry that you potentially upset the timing of a good relationship, but having sex too early. THen ask her all the questions you mentioned above. See what she has to say at that point.
