Silent sex??šŸ˜©

When my boyfriend and I have sex, he rarely ever moans. I feel as though he thinks it's because he is a man and moaning is feminine. But, I have to constantly remind him that moaning is a turn on for me and he does it that one time and the next time he's silent again. It's honestly super awkward when I'm the only one making noise. I don't know what to do. Any advice??Ā
