That is the main reason you were able to get a second one. Remember, second dates are usually about trying to discover that chemistry with each other.
This time, it may be okay to involve some physical aspect into your date.
You can always tell by her actions and how she receives your physical signals. No matter how extensive your planning or preparation for the second date may be, always remember that the ultimate goal is to enjoy and have fun with your partner.
If you and your date is able to enjoy the second date, you still succeed in your goals.
Ask your date about his or her favorite things to do, and go do one of them.
