Well, about a week or two ago i had this burning feeling while peeing. Then my penis started to get really sensitive. I'd be at work and it'd be so hard because when it would come in contact with my boxers/pants, it would hurt really bad. I went to see a Dr, thinking maybe it was a Bladder infection or something. But the tests came back negative. I'm not really sure what to think of it now. I have an appointment with a Urologist, and i'm kinda scared that maybe i have an STD. I have a pimple on my shaft, but i didn't think anything of it because A) it was only one B) I thought it was just cause of the hairs because it had a white puss. But i don't know what to think now
