My SO and I are both pretty quiet in bed. It took us almost over a year to get louder but we are still pretty quiet. She likes when I make a lot of noise so I try to be louder for her but other than that the sex is amazing and as long as she is enjoying herself I don’t care how much noise she makes. It does excite me more when she openly moans but I love her so much I’m just happy to be with her. I think the longer you are together the more comfortable and open you’ll get together. Just takes time. And like other people have said here; she may be quiet but she is really animated in bed so I know she likes it. She takes charge sometimes and start matching my pace. Idk if this relates to you in any way...
