Girl on Girl: How can I make our first time special?

This is extremely odd for me to be asking but how can I make me and my boo's first time special. We started out as really good friends before with occasional flirting until one day we were drunk as hell and ended up making out. Ever since we haven't been able to stop and its becoming so intense that I know sex is soon to follow. Usually when I'm involved with a girl, I'm the aggressive one and typically the more boyish one and it's a one and done situation, but I really like her and want to see where this goes without messing up out friendship. Help!!!!
