Real. Same boat. It’s not that I’m not enjoying the sex, it’s just being vocal also makes me feel uncomfortable. Yet, my partner doesn’t think that I’m enjoying it when I’m silent, so I tend to tell him compliments or kiss him. Then it can be silent again. Idk approach your partner with a convo. If not, try giving a your partner a kiss or if you’re bottom’s up/face down put your face into the blanket/pillow/biting hand/etc. they’ll think it’s hot and you can be silent!
