Being loud!

My boyfriend has the most squikiest bed in the world!!! When we have sex his sister & mom are in the living room. It's so hard not to be loud so I put my face in the pillow but I still feel like I'm loud cause the sex is so bomb!! But after I walk out to go potty or anything I feel so awkward like they heard us. Or the heard me moaning so loud. Do you ask someone if they heard you or just leave it be until they say you're being to loud?👀
