Recently, I have been tested negative for chlamydia, gonorrhea, and HIV. Then, I went to another clinic just today to get tested for the same three along with genital herpes/warts. I don't really experience any symptoms, no burning sensation when I urinate, no pain in penis, no milky discharges, although sometimes I feel a little itchy but I don't pick at it cause I feel it would only make it worse. I had this one lump located on the back of the shaft and of course I had to pick at it with both my index fingers and a string-like pus came out and left a mark. Now, I've noticed when I shaved the shaft area (which is irritated) that I have these yellow little bumps scattered on the bottom of my penile shaft. I honestly don't know what it is, hoping that it's not something serious and easily treatable. I've been with two women and one was unprotected and the other was protected, but they have both informed me that they do not have any sexual infection of some sort, so I'm basically going by their word. Please take a look and see what you think! I am also uncircumcised if you are wondering.
