Novel environment roleplay
Even at home, try to recreate the vibe of a novel scenario: “Let’s pretend we’re sneaking around in a dressing room,” so you only partially undress and have to be quiet; or “This is a one-night stand in a hotel” so you act more like strangers, maybe meeting in the living room “bar” first. The feel of a new setting (even if imaginary) injects excitement and can lower inhibitions.
