Suggestions for being quiet?

Natalie • 29, live in Ft Worth Tx, kinda living with a guy I known 8 years, we`re 2gether but we`re not. Not fwb, no other ppl.
So my boyfriend has a roommate and when we have sex I have to be quiet, only there's one problem I orgasm extremely easily and I'm a screamer. Which in turn leads to another issue of me unintentionally pushing him out. So what I'm looking for are suggestions to be quieter and ways to keep back from orgasming so easily.
