I have a red bump on the shaft of my penis and it was there about 2 days after the contact. it is not blistery or pussing at all. just red mark. One morning I woke up and there was dry skin on top of it.
Are you for sure it was HPV that you were exposed to? Sounds like it could maybe be herpes. Think you should make a doctor appointment and have it looked at while the red mark is still there. That way they'll be able to identify exactly what it is.
