I ve had an itching sensation on the tip on my circumsized penis for around a year now. When I pee, it seems to relieve the itching. Std tests have come back negstive. I normally masturbate about once a day. I stopped wearing boxers and wore basketball shorts and that helped, but now the itching is coming back. If I don t itch it, it doesn t itch for long but if I accidentally touch it, the itching sensation is still there. I have also developed an intense sensation to pee regularly so I m thinking that could be a uti. Could a uti cause this itching? I have seen many doctors but they don t know the problem
