Just listening to the sound of a heartbeat, seeing someone’s chest move from their heartbeat, or feeling someone’s heartbeat turns me on for some reason. This is weird but sometimes when I masturbate, I put one hand on my chest or listen to the sound of a heartbeat.... anyone down to send me recordings of their heartbeat and breathing?
I've had lovers comment on hearing my heartbeat as they lay on my chest in the after glow. I think it is a comforting and secure sound to hear for a woman.
