That's true, I use werewolves in the wild penis model from Noir since i find it the best looking one but there a lot of clipping issues in some animations, specifically with bigger booty female sims. I find that the default one works the best.Simdulgence overlays are good for SPECIFIC attachments he made, they will not work with all cocks. It is unlikely the overlays will work for the WW penis unless they use the exact same UV map. I might open S4S to examine the WW penis later on. Honestly, I never use it because there are nicer cocks out there to play with in the game. Cheers.
