In the 80s, my turn-on was hearing the session start with the usual kissing and soft moans. Then there'd be a quiet space then you'd hear the sheets rustling louder and louder almost to the point of being white noise - coinciding with her increased grunting and moans, louder rustling - screams, gasps grunts, begging to be gentler, then his roaring orgasm.
I'd love to hear that again; I think it's 10x sexier than bedsprings.
Unfortunately, most don't screw under the sheets anymore - and I understand. Multiple positions, doggy style - you can do so much more in the open. But if any willing couples occasionally post their sessions here (hint Dr. Cruzsilva?) ...
