Yes, sharing music was the first thing I did that was beyond just talking. Yes it was scary. I have since shared lots of music, tv show/movie clips, and a world of other things.

I will often use something like these as a way to explain my feelings or introduce a topic.

My T has always been receptive to whatever I bring in with a interest as to what it means to me.

Good job stepping out of your comforts and giving it a try. I hope it goes well.
