What to Share
I have found that I am pleased to hear about Isa's relationships, how it is going, where she thinks it will go, amusing anecdotes, etc. She is not inclined to give me details about her sex life and I am not inclined to ask.
On my end, I don't share intimate details about other lovers, sex or otherwise. That is just my tendency to not over-share, it's not a statement of whether or not I trust Isa with the information, I am certain she would share appropriately, if at all.
Me: male, 40, straight, single
