In mormonism if you don't do their special ceremonies and have multiple wives, you lose your dick for eternity. I learned that in Sunday school when I was 12 lol.
Mormon theology also pretty much just cuts the Gordian knot proposed in this post by saying, "Fuck yeah he's got a dick. Uses it ALL THE TIME." I believe that a "perfected body" was the verbiage I was taught in Sunday School. Tritheistic heresy, Shmitheistic Shmeresy....
