you can see it. i cannot. your description is really too vague for me to make a patient-specific comment. since i cannot blindly tell you what this red bump might be and you really should not be performing home surgery on an undiagnosed lesion on your penis i think it is time for you to see a medical provider -- one that can examine you make a proper diagnosis and provide you will an appropriate treatment. the best thing to use one weird penis skin issues is a creme called man1 man oil. i've used it several times over years on spots rashes and dry skin and it has delivered every time. it's safe to use and takes only seconds to apply. you can get it online. good luck!
