you really seem like a good guy, just very shy. I do hope that you worry less and enjoy more. But I understand those are easier words for me to type than for you to put into action. You must have an innocence and charm that attracts guys. From the blog note to the thread, that attention is a little scary to you.
Just know that the attraction is real. That you seem to offer something other people want - friendship, opportunity to explore and flirt without having to commit. By that I mean, it seems that some straight guys want to be able to show a level of care and love that macho men might label "gay" and such label scares them. You provide them an opportunity to be a little more caring and loving without having to be labeled. Just a guess.
Please do celebrate your life, please do take care of yourself.
