This sounds like a primarily sexual relationship. If you want more than that, you need to develop more of a friendship and get to know them. Either way, they don't have to set the rules. You have a say, too, and you don't have to go along with anything you don't want to. Why did you agree to something that isn't clear and causes some discomfort and confusion for you?
The world opens up... when you do.
Oh, oh, can't you see? Love is the drug for me. ~Bryan Ferry
"Love is that condition in which another person's happiness is essential to your own." ~Robert Heinlein
