I had an athletic partner with a resting HR of The bed shook with each beat of his heart! I was with a guy who had an arythmia addressed by electroshock. His heart has only two speeds. So, even when he's excited his heart stays slow for a while then suddenly goes to its "fast" speed.
Only once very many yaers ago I met one guy whose heart was felt well each time I touched his chest. I could put my hand between his nipples or right below his left nipple and I felt his strong heartbeat under his skin. When I put my stethoscope on his chest I heard his heart beating very loud and very strong. At nights I only touched his chest a little in order to feel his heart.
When I put my stethoscope on his chest as he was asleep he never awoke. I liked a lot to sleep with him because I could listen to his heart at nights also. Many other guys did not have his hearts listened so clearly. I often ask them to be quiet and do not move when I am auscultating their hearts. So I need to press my stethoscope very firmly to their chests in order their hearts be listened well.
Looking forward to do that again with my Wife I would play with her pussy while listening, it was always incredibly erotic and a ton of fun for both of us. Heart auscultation is very exciting and you can also listen very well lungs no need to as for deep breathes because the breathing is intense and heavy enough!
I had done this with ex and firl friends, I don't do sex with play patients but can have them masturbate and listen at same time I can tell exactly when my partner is going to have her orgasm. The sound is going rapid! Then she is turn will listen to me as I cum. With my first girl friend, who was into stethoscoping as well, we started.
First, she listened to my heart, when she masturbated me. Then, I tried to steth her during making love. It was only possible when she sat on my cock, so, I had her upper body infront of me and could reach her heart region. But to listen, we had to stop movement. And during my orgasm, I couldn't listen, but immediately after her orgasm, I could very well listen to her excited heartbeat.
For me nearly a second orgasm
