15th Birthday Party Ideas

I am having a 15th birthday party in March and I don`t know what to do. I want my party to be held at my house and have both guys and girls there. I have searched the internet all day looking for ideas as to what both guys and girls would want to do and I found nothing. Does anyone have any good ideas? Oh and my guy friends aren`t too outgoing, so they aren`t into spin the bottle or seven minutes in heaven so any other ideas would be helpful:)
