First date from an online dating site
I've had multiple instances where after the date, some friend asked me "So where does she study? The most important thing for almost any girl is how a guy can make her feel, so just propose a walk in the park, on a beach or through the woods, or whatever with her by saying that you're tired of going to cafes on dates and so on and you'd rather go for a walk instead, then just go and have a fun time together.
If she has a wonderful time with you when on a walk, she won't care what you have or don't have and a second date will be pretty much guaranteed.
Also, try not to make the date sound like an interview! So don't overthink things - focus on having a good time together, the rest will sort itself out when you both like each other.
I realize my date may have not felt the same way about it, but I would at least wait a day or two then tell the other person that we had a great time but I’m still talking to other people.
