Thanks. Thing is about the 'not trying' thing, it's nonsense as I have endometriosis, so 'trying' is actually quite a difficult and painful thing for me (if I don't do it right) so it always has to be planned (no spontaneous bonking here I'm afraid).
So how can we not 'try' 
Or maybe all doctors think it happens like in the movies, where they leap into bed and his willy practically falls into her fanjo and they're at it like rabbits in nanoseconds
Like Ben Elton used to say, Tom Cruise's knob must have velcro on because it always seems to find its target straight away. Most normal people have a few minutes of wriggling and shouting 'Not there, not there, up a bit!' 
Well, now I have lowered the tone, I am off to visit my elderly parents 
Good luck to those still 'not trying' this month.
