Solved. Thanks!
For some reason my male sim have pitch black penis even though their skin is pale.
I try to see if it was my CC. Thus, I removed all my cc/mod and only have the wickedwhims mod file.
I found out that my sims (stripped from all CC) still get black penis.
Still with no CC just wickedwhims in my mod file: I when into creator sims and created a brand new male sim, I added the new sims into a household with my original sims (that use to have CC).
