I agree with your self diagnosis. This sounds most like Angiokeratomas of Fordyce. This is absolutely, in no shape or form, related to any type of StD.
We do not know the cause of this, but some authorities feel that they are due to increased venous pressure ( perhaps, from a varicoele).
No treatment is needed since this is generally just a cosmetic problem. We have found the 1064 nd: Yag laser quite effective, so if you really want treatment, this is what I would recommend.
I would be happy to answer further questions.
Ok thanks I'm based in North London is there somewhere private you could recommend to explore Yag laser treatment?
You might try Mark Hudson-Peacock. Please let me know if I can be of further help.
