I agree with what Chelsi said. DH has no problem with being vocal in the bedroom, but I do (I'm so afraid I'm going to disturb our neighbors). However, he loves me being vocal, and he tells me that. So even though I try to hold
back at times, it just escapes, and while part of me feels a little embarrassed, I can tell that he gets a real kick out of it. It may be that your guy is kind of quiet anyway, and if he is, that's okay. It may be that he's still a bit
shy, so find ways to get him to open up and trust you. Sometimes doing something new can work out--it may be scary, but reassure him. Continue to build that trust in the bedroom.
