Ok, first off.. if you are over the age of 15 then you need to ask him yourself. DOn't let your friend do it. It will make you look childish.
Next, a first date should be VERY generic and should be something easily escaped from. So keep it simple and informal. Also, something where you dont have to talk the entire time is nice. Which is why movies, plays, shows work great.
Going to the movies, while over done, is still a very good first date. Not to disagree with Gemma
, but I think the fact that you DON'T talk much is what makes them so perfect. IF you are forced to talk too much on a first date it always turns awkward. Concerts are also great.
ALso, if there is something you do that is unique, if you can incorporate that in, its usually pretty cool. Like I had a girl invite me to an art show she had some work in for a first date. That was pretty damn cool.
Also, afternoon dates are underused because they are usually short but they are great for getting to know someone. Meet for lunch, or to go to the mall or a matinee movie. These also let you escape easily if the date goes bad.
