Hi Caliyr,
I guess since you have everything 'up to date' or your profile, so to speak, most people will be able to put 1+1 together for themselves.
People won't just bring it up though, out of social convention. Many will just be trying to be polite. Some will be unsure how to react. Others may not been paying attention!

If you want to clear the air then definitely, some kind of announcement is the way to go.
I'd avoid writing thousands of words, just by virtue of the fact that many of us have short attention spans ;~)
Say what you want to say, make it clear and concise. Say this is who you are and how you live your life, and that you are a whole world better for it.

How people will react is out of our hands - but do not fear that. In general, a comfortable, authentic and genuine person - the real 'us' we are all striving to be - will attract good things into their life.
It's also more than likely that people will begin to approach *you* for advice!
All the best x
