Unidentified skin condition

About 8 months ago I developed a weird skin problem in the area around my rectum and below my scrotum.
The only way I can describe it is that if I scratch or rub any part of the area fairly hard 5 or 10 seconds later I experience a feeling of "after-burn" in the same area. It is a fairly uncomfortable tingling or burning sensation.
There is generally nothing to see except on one occasion one doctor did say that he saw slight reddening and cracking of the skin in the area.
It generally does not make its presence felt unless provoked!
I was tested for the "usual" STDs which were negative.
It does  not seem to have spread geographically from its first appearance but it does have "good days and bad days".
I have been prescribed variously mild steroid, anti-fungal and anti-bacterial creams none of which seems to have had any noticeable impact.
Curiously I was once prescribed Trimovate cream which did seem to have a beneficial impact but the condition soon returned once I stopped using it.
Any thoughts?
Is it likely to be transmittable?

No.

You seem to be describing the sensitivity common to a thin-skinned area like the one you're talking about.  This can be provoked by friction of any sort.  Cortisone creams can help a bit but repeated use loses effectiveness.  This doesn't remind me of any STD.

My advice is to use a light moisturiing cream daily after washing gently, and that's all.

You put it well by saying: "It generally does not make its presence felt unless provoked!"

Don't provoke it, and you should be fine.

Best.
