Calm down folks. 

Pumeco is correct - male genital mutilation is primarily a christian/jewish thing. It's part of their religion, so you're going to find it most often in areas where those religions dominate, even when those practicing it are not necessarily religious. Thankfully it's becoming less common in the U.S. but it still happens every day. Personally it should be outlawed, as it is no different than female genital mutilation, but you rarely ever hear it referred to as such, for obvious reasons. 

Anyway. I'm pretty sure all the male Poser figures have a foreskin option. Some work better than others.

@Toastie: The ULF gens take M4 textures. And to correct my previous post, I don't think Jepe is the original creator, he just makes a lot of add-ons for them (or made, as I'm not sure he's still an active user).
