in the 1920s, people barely had recorded music to listen to
if you wanted to have sex to music in the 1920s, you'd have to hire a band to play in your bedroom, which i imagine would get awkward.
"a one two thr"
"do you guys play by ear? we want the lights off."
and even if you had a phonograph and a wax roll to play on it, they all sounded like Tiny Tim.
"oooh aaah lalala *plays tiny ukulele*"
