I've noticed I have 4 small pimple like bumps on the shaft of my penis. I kept picking one and it looks to have a bit of dry skin on it now. I'm sexually active with my partner of 12 months and have not really been in one night stands. They haven't grown in size when I squeeze them nothing comes out. They are not painful as well. They have been there for few weeks now..has anybody had the same issue?
