Although it's all just roleplay, those in control of who uses such pregnancy systems as EDEN or Mama Alpha do require that you become "certified" to use their products regardless of the fact that you can buy them on marketplace. And in fact, must purchase said systems before you can train in how to use them.
On top of that, I'm learning that the entire roleplay has somehow become highly biased against men. I personally have been denied use of the Mama Alpha system due to my gender and am starting to wonder if that is the same thing I'm facing with the EDEN system.
Simply saying........ Think it through before you decide to use such systems for your roleplay.
