Being uncircumcised roughly doubles the chance of catching HIV if sexually exposed to the virus. This is a big deal for public health and the frequency of HIV. In some countries, if all men were circumcised, the frequency of new HIV infections in men will be roughly half what it would be without circumcision. This is why circumcision is being promoted strongly in places like sub-Saharan Africa. On the other hand, "double" doesn't mean very much for most men in industrialized countries. Since you always use condoms, and probably few if any of your sex partners is likely to have HIV, your risk of HIV in the next decade might be, say, 1 chance in 10 million if you had been circumcised. Doubling that makes the risk 1 in 5 million. So despite doubled risk, your chance of getting HIV is zero for all pracical purposes. (Higher of course if you have sex with men or otherwise are at especially high risk of HIV.)

Your other questions all have to do with genital hygiene, not really an STD/HIV issue, so my comments are brief. As best I know, your own normal care (daily foreskin retraction with washing) is all that is necessary. How you urinate makes no known difference in risk of balanitis or any STD or other genital health condition. To my knowlege, the large majority of uncircumcised men do not wipe after urination and I see no need for it. In other words, I agree with your urologist.

I hope these comments are helpful. Let me know if anything isn't clear.
