Bedroom tips??

So I have a newish boyfriend, we've been seeing each other like 2 months and have PLENTY sex. But idk how do I make it more exciting in the bedroom?? Like any tips at all. Whether it be how to tease him or just how to make sex better?? I'm quite a shy person in bed so I usually let him initiate and I don't do much but I want that to change, please please help💖 thank uuuu in advance
