HELP.

I am need of some help when it comes to the bedroom. My and my boyfriend have been together for nearly 3.5 years and we enjoy having sex together, don't get me wrong, but I feel like I don't 'help' enough in bed (if you know what I mean)
So I need some advice on how to 'help' more. We are going on a holiday with each other in a couple of days and I want to make it special for him. 
Please help a sister in need!
