Just to be clear... When Pentax users say 'bayonet' they are referring to the K-mount as opposed to m42 fitting, which is screw mount and requires an adapter...
If your sigma lens does not fit K-x it is either:
1)Faulty (or damaged)- possible the mount is bent slightly...
2)bayonet fitting (but not K-mount - perhaps nikon-F or olympus...)
3)M42 (screw thread (this will work on K-x but will require an adaptor..)
With regard to your search for a macro lens...
I too would really love a decent macro and intend to save for either a Tamron 90mm macro or a Pentax-FA 100mm f2.8 macro lens... But looking at around £300+

Are you sure your Sigma lens is a Pentax bayonet Trixie? There are many other types of bayonet fitting for different makes of camera.
All the Pentax branded bayonet lenses will fit your K-x so these will not be a problem. It's best of you choose one with a Ka bayonet though, so that all the electronics couple with your camera and you don't have to mess about with manual settings.
You can tell suitable lenses as they will have electronic contacts on the mount and an "A" setting on the aperture ring. This includes all manual focus SMC Pentax-A lenses and all autofocus ones.

you would be better off if the lens you are interested in has a bayonet fitting
As for Macro lenses Trixie you could also consider the Tamron Macros, they can be every bit as good as Pentax and can be picked up for quite a reasonable price in KA mount too.
Thanks to everyone Cheers Trixie

It will fit but you'll have to use stop-down metering which is, to be frank, not very accurate. OK for flowers as you can shoot, look at the histogram, adjust, and shoot again but probably less helpful for bugs that don't tend to hang around while you adjust the exposure. An 'A' series lens would still be manual focus but easier on the exposure.
