this started only a little while ago, but i'm a little worried, recently almost any time I urinate, and sometimes during ejaculation, there is a slight "burning" feeling in the very tip of my penis. I also found that if I apply slight pressure with my finger just under the head, on the underside and slide my finger around, there feel to be a sort of, I guess, "scratching" feeling inside. it's not really pain, but I'm not sure exactly how to describe it. can anyone give me some advice as to what might be causing this?
u could be having an allergic reaction to a condom
Get an STD test. There are lots of horror stories of men that don't "fix" this type of problem and then have problems for life or longer term.
