hahaha, i had the same problem this summer, and let me tell u, i was nevervous as heck to ask my gf( witch we are in a realation right know )
dose see have friends that are yours to? if so, all of u go to a place together, then at the end, ask her the come somewhere close by ourselfs and ask her then, if u ask her starit off it well be a really weird still being w/ them. as for the first date, a movie is perfect( we went to Step Up, lol)
And mabye u guys might get a kiss into it!
hope it work out
