I suppose I have to pleady guilty to the charge of obsession.

There may well be something unhealthy about it, but I think for me it has been almost inevitable — for a start as a young guy with a lot of anxiety I could indeed have done with some "support", and some advice, but didn't get any. So there's no harm in passing on a few pointers to other guys, if they can be of any use. The other point is purely physical ... as I get plenty of reminders of my size every day, for me as Donk says, it is inevitably part of the picture.
