Welcome to our Forum.  I'll be glad to comment. Clearly that you still feel that there are problems which you characterize as NGU 2 years after the event suggests that this should be evaluated.  Have you been evaluated by any of the superb genitourinary medicine experts in the UK?.  The symptoms the you mention, both soon after the exposure (rash, change in appearance in your glans) and more recently a sensation of less forceful ejaculation are not typical symptoms of NGU or any other STI.  You are correct the the meningococcus can occasionally cause urethritis in men but when it does symptoms are typically an obvious urethral discharge and white blood cells evident in urethral smears.  Did the testing you had include a Gram stain or test for white blood cells in your urethra, one of the hallmarks of NGU?  Have you taken any treatment and did it make any difference?

I will likely have additional comments after you reply to my questions but at the moment, with all due respect, this does not sound like NGU. 

Looking forward to the additional information you will provide. EWH

Thanks so much for the additional information.  In the absence of white blood cells on two occasions, it is very difficult to call this NGU.  This is not to discount  your symptoms but I find it hard to generate evidence that this as an STI.  The other question I would add for completeness sake however is to make sure that your testing including testing for Mycoplasma genitalium which can occasionally be a cause of persistent urethral symptoms. 

My other comment has more to do with personal experience than science-based data from research studies.  When I have seen patients who have had persistent urethral symptoms, as difficult as they are the good news is that there is no evidence that those symptoms represent a threat to the health of sexual partners, nor do they progress to complications . Instead if anything they tend to decline in severity over time, as has been your experience. 

I have to say that as well that there are certainly instances when the presence of symptoms such as yours tend to lead affected persons to concentrate and become increasingly aware of sensations which are normally discounted or overlooked.  I cannot help but wonder if this observation is helpful as well.

I hope that this information is helpful to you.  EWH 

Thanks.  I think having a mycoplasma genitalium test you have confidence in is a good idea.  Presuming that is negative, I can see no reason whatsoever for you to not "get back in the saddle".
