Skin Problem with male fit S2 sims

[pioupiou]

I have noticed a strange problem with my S2 fit male sims : the skin used for their bottom body is incorrect.
I'm using default remplacements for the maxis skintones ( allan akbar's ones).
As far as I can tell there is no problem at all for females, and I only noticed this problem on male sims when they are fit. I noticed it for adult and young adult. Teens and elders I don't know.

Here are 2 screenshots to better explain what I'm talking about :





My sims using custom skintones seems to be fine.
What puzzled me is that I only use the female replacements for the default skins, (in order to have nipples on them). Next time I play I will take out the default replacement and see what happen with the maxis original skintones.
Any ideas on the problem much welcome
Thanks

Do I spy a mathman mesh lurking there?  Cause I had the same thing when using that.

I use Crammyboy's one. I haven't tested yet how it behave without my default replacements.

Yes, that looks suspiciously like a penis mesh that causes the problem. I used mathman's penis mesh and sure enough, I noticed the same thing. Then I tried Crammyboy's alternative and all inconsistencies were gone.

ETA: I use default skin replacements from paradisesims.

I don't understand why it only happen for the S2 male....
And DrBeast are you sure you didn't have problems with crammyboy's penis mesh ? Cause that's the one I'm using, so maybe my issue is something else ?
Thanks for your response

100% sure, I've been using it for an extensive period of time and my sims are frequently in the buff. I haven't tried any other default skin replacement besides paradisesim's ones though, so it could be skin-related.

Interesting, I noticed a similar problem with a S2 fit sim and I use crammyboy's penis mesh.  He was the only one I saw the problem with and though it wasn't as pronounced as yours is in the pictures, I could still notice some slight difference.  I wonder if this only occurs for this particular skintone as I've never seen it happen with any of my other Sims.  I use Enayala's skin defaults and Sim Cribblings.

I'va done some testings in my clean version of the game (no hacks, no custom content etc, mainly for testing) : with or whiothout crammyboy's penis mesh I have the same problem on male fit sims of S2 skintones.
I've tried with and without the default replacements I use (allan akbar), with and without the penis mesh, and I've tried some custom slins to compare (and the alien one). The only one with problem is male fit S2....
I really don't understand.
If someone has ideas for additionnal testing I'm open to suggestions.
thanks
