I disagree - the ED nurse or andrology clinic usually know far more about what the CCG will pay for, which meds can be used together, etc and generally will have the time and capacity to give you and your partner any counselling or support you need. However, it may be Ulsterman that your CCG doesn't provide an andrology service and that is why the urologist leads on it.
Our urologist is the best thing since sliced bread and is genuinely interested in what John tries, how it works, how successful it is, etc but he referred us to Zoe on the basis that she was the expert (his words, not mine). That's our particular part of the country.
Betty, he could probably use the vacuum without using the rings as long as he isn't too vigorous with it - it would help maintain penile health even if you are not using it for sex.
