Like barmaid, I haven't read the thread, so I don't know what the consensus is but here's my answer.
Chris Rock (American comedian) says 'women have platonic man friends - men don't have platonic woman friends, we have just women we haven't f***** yet'., and at the risk of making us sound like animals, I'm afraid it's pretty much true.
Barmaid has a great friendship with a man, but the key thing is AFTER they were a couple. If that coupling had never happened, he'd pretty much still be wanting to jump into bed with you.
