My (26M) girlfriend (24F) wants me to tell her she's doing good during sex.... But I'm not comfortable with that

I’m struggling with this issue and would like some feedback on how to navigate it. My girlfriend of a few years has recently asked me to voice my pleasure during sex. I struggle with this because I can’t bring myself to do it. It’s not that I don’t find her attractive or pleasurable, but it’s something I can’t bring myself to do. <br><br>I would very much like to overcome this, but I’m not sure how and I’m also worried about hurting her. <br><br>What would be the best way to handle this? <br><br>I’m uncomfortable with telling her she’s doing good, but I don’t want her to feel inadequate or like she needs to change.
