Am I overthinking this?

So me and my boyfriend will be together 10 months on the 29th and recently we have became more intimate. He has made sure that I know we don’t have to rush and I know that. I also started calling him daddy. And also we have been doing things over the phone. You could call it phone sex. And for the past almost week we haven’t done nothing. And I feel like whenever I try to throw hints at what I want he just goes to another conversation. But he has also said that he loves it when we do it. I stopped calling him daddy for the past couple days and we talked about that today. And he said that he can see what I’m talking about but there’s nothing for me to worry about that he just doesn’t want anyone to hear us. And I understand that but the only time we do things is when I’m positive no one will hear us. It just makes me really scared that I’m doing something wrong or he’s just gotten tired of it. Dose anyone have any advice for this. Because I’m scared and I don’t know what to do.
