In on March 12th, I just finished masturbating when I felt an irritating tingling sense on the underside of my penis (or urethra) accompanied by a red patch on the urethra. It is now May and I still have this feeling and I don't know what to do. A potential cause is that I was using a soft blanket to masturbate with instead of using my hand, as I do not like using my hand. However , since then I have tried different ways and even continued using the blanket only now I use lube and latex gloves to protect my penis from rugburn. I have gone to the doctor and he didn't seem to know what the issue was, he prescribed me an antibiotic in case it where an in infection. I finished the prescription and it did nothing. I even went without masturbating for extended periods of time. But that only seems to make the feeling much worse. However, there is a way to slightly counter the feeling, If I hydrate myself really well the feeling will go away until I dehydrate (or urinate). sometimes I feel so desperate to stop the feeling that I will hold in my urine for extended periods of time just to keep the feeling from returning. If anyone knows what this might be please help! I'm tired of having this and I don't want to start college with it still there.
