I've been very clear in my replies that I do respect those boundaries. Some people don't want to be touched. This has been heard, understood, respected by me, and there is zero counter-argument from me. There is no lack of understanding or need to correct me on this point.

And the incident I recalled did no long-term damage to our friendship. It was a hurtful moment, I got over it, I didn't push the issue, and we're still friends.

The point of the OP's post and my first comment is to try and address how unfortunate it is that the cultural default is: men hugging is icky and gay.
