I wonder why my scorpion friend warned me not to discuss my sex life with anyone

So one day I was discussing about marriage life with the Scorpio guy who is my friend and on whom I've crush.

I somehow went on the topic of honeymoon night of my friend (girl). So I told him that how my friend shared everything about her first time and all. He was listening everything but then he got shocked and told me that, I should not ask anyone about their personal life and sex life, it ruins the privacy and all. Somewhere I did felt he was right and then All of sudden he jumped up and warned me "you better not share about your sex life with anyone no matter how close you are with that person, it should be with you and your husband" he kept on saying again and again until I agreed to him. At that moment I felt like as if he was going to be my other half and making me to be careful about us.

I wonder if had said that to me out of concern or if he had something for me!

And later after our discussion on my friends sex life he asked me with a playful smile "so what you think about it or feel about it(sex) after listening to your friends story" and I just blushed and smiled and shake my head giving not much response. And we both kept smiling. 😄
