I have red bumps on tip on head of my penis. Not itchy or bothersome just troublesome to look at. Used condom but didn't shower for rest of day.

See answer. Red bumps on the head (glans) of the penis most commonly caused by either irritation, infection, or a specific type of dermatitis. Irritations can be related to trauma or specific irritant (chemical, spermicidal, lubricant, medication, etc). Infections more common in uncircumcised penis and often fungal/yeast (especially in diabetics) or std like hsv. If does not resolve with good hygiene, see md.
