There has been the odd moment where I have wondered if I've taken things a little too far. It could be the difference about 5 seconds and I realise this might be the end of it, the end of the feeings that make it worthwhile. But an additonal 5 seconds could change the whole outcome. Once it has subsided and I realise I'm back to the beginning I have a desire to start it all over again and see if I can recreate the same or even better feelings.
