Communication during sex

Destinee • 22 • Engaged ❤️ • newly pregnant 🤰🏾
It frustrates my boyfriend that I don't speak up or make any noise at all during sex. He says it's hard for him to know what I like. In my head I'm saying everything he wants to hear but it's really hard for me to let it out vocally. I am very comfortable with him, it's not me being shy. Does anyone else have issues with this. Any suggestions?
