tips on "taking charge" in the bedroom

Brittany
So last night my boyfriend and I were making out and things were heating up when all of a sudden he just stopped. I asked him why he stopped and he said he wanted me to take charge and to "take what I wanted". I'm not a "take charge" kind of person anyway so it freaked me out a little bit. I asked him if he was starting to get bored and he said no but, he said that he wanted to change things up. I didn't know what to do or how to take charge. I would really love some tips on how to take charge in the bedroom. I want to show him that I'm not scared to take what I want when we're being intimate.
