It is difficult to be present with people you know will grow uninterested in you. It is difficult to develop friendships knowing your value is temporary.
It's not just that I never had a childhood best friend; it's that I'll never have a childhood best friend. That era has come and gone, that chapter closed.
One day my friend came home and found me in deep emotional turmoil. He directly asked me what was wrong, so I tried to explain what I was feeling about him.
I was best friends with a straight guy. We could live together and share hugs and other brotherly affection without worrying about falling into sexual sin.
I told my best friend that I had literally just come from gay sex in another man's bed. I'd found him on the Internet, then regretted it. I needed support.
