I just went to the doctor on Tuesday and have been treated for a UTI after giving a urine test due to developing the sign and symptoms over the weekend so I'm on meds for that. I'm a 25 year old male. Tuesday night I noticed what appears to be little red pimples on the right side of my shaft. One on top of my penis head and a small sore/lesion to the right directly next to where my foreskin begins. I'm freaking the f**k out. I'm sexually active but only with one girl that I've been with since January. Could this happen due to the UTI and the skin is reacting to the infection?
