Mistake number one: you're already thinking too much into it! Don't plan the future, just go on the date and let things flow as long as you have in your mind not to push things too quick.
Secondly: virgins tend to be a lot harder and that's the honest truth, they all have this princible that they only wana lose it with the right guy lol

so you're task is to show her you're the right guy for her. Make her trust you and she will do as long as you don't hint sex to her.
YOU DON'T HAVE TO TALK ABOUT SEX, and the less you show any interest in sex, the more respect she'll have for you. Might sound stupid but a lot of virgins get freaked out when the sex topic is dropped in.
Gona be a long journey for you but as long as you play it kool and well then you're in
