Well well well, I'm barely out as bi and I decide to go and be polyamorous as well...
Friends have suggested it would be interesting to read about my experiences and I would like to get some of it down, so I'll try but we've missed the first few months and many many thoughts & feelings about it, so apologies if this is nothing more than a fragmented account.
If you're interested in polyamory obviously wiki search it and then perhaps check out
http://www.polyamorousmisanthrope.com/ We also read The Ethical Slut by Dossie Easton and Janet Harvey, which I can't recommend enough.
So my partner was 2/3 of the way through the aforementioned Slut book when he was asked out at work. Bless him, he explained the whole thing and bless her, she batted nary an eyelid. What followed was a week of very late night talking & emotional honesty that felt not so much like therapy as it did like religious epiphany. All that has quietened down now but there are still moments, believe me. These moments can feel like you've been torn to shreds by a pack of starving hyenas but the good thing is that your worstest fears have been realised and not only are you still standing but your partner still loves you (and quite possibly other people love you too). And when the fear has been taken away, what follows is, well, exciting!
So I've recently been thinking about a few things: jealousy, coming out at work, telling my mum (I did it!) and meeting the other lovers.
If you'd like to hear more please comment.
