Pimple like bump on penis
Today, when I went to take a shower, I noticed a semi-medium large bump near the
Bottom of the penis (I guess, near the sac), anyway, I pinched it and a small amount of pus/white stuff came out. The bump isn't any color (Except my normal skin color). Only a small amount of white puss came out. No blood or anything. It doesn't hurt when I pee or do anything with it. It only hurts now because I squeezed it to see if I could get anything out of it. That's the only thing that makes my penis hurt right now, is because I tend to squeeze to hard and end up hurting myself. So, after a few minutes this small pinch pain should go away.
What could it be? STD? STI (I think that's what it's called)? Or is it nothing to worry about?
