I have always found location and interests to be more important than sexuality when choosing practise partners, but if I lived in London perhaps there would be a larger NLP pool to dip in.
It's interesting that some people thumbed down Adam's post and I'd be interested to hear their reasons for doing that.
From my perspective, I prefer practicing with the brightest and most varied bunch of people I can find... but part of the joy of life is that we're all different, and I don't see any problem with what Adam's asking for.
I change my mind often; I might not agree with this any more
