I don't know if i have aids on my penis or what it it?

Get tested? : HIV virus is not visible to the naked eye. If you are describing something on your penis it may be another STD... Get tested!

Go see ur Family Doc: Or at least go to Planned Parenthood (yes, they see guys, too) or city/county health department/clinic. While I have no idea what "it" looks like, I can reassure you that HIV doesn't usually present as anything on penis. And it takes a while for HIV to progress to AIDS. However, there are more common sexually transmitted infections/diseases such as syphilis, warts & herpes etc http://goo.gl/Hs4Wi4
