Funny that you mentioned cultured meat. Do you know how that is made? What they do is get baby cow fetuses, taken from slaughtered cows who are pregnant when they are killed, and stick a needle into their tiny hearts while they are still alive to drain off their blood and then sent it to the lab to use to grow this cultured meat. Do you really want to eat lab grown meat after knowing that?

As for creating a realistic penis that's a sci-fi fantasy. It's not possible, and it won't be possible in the any currently conceivable future. The current process is mad scientist levels of crazy that no one should be allowed to do.
