Something I've been thinking about for years now. Every now and then you read an article or see a video about how they're 3D printing human ears and bladders, making scaffolds for cells to grow on in tissue engineering, and at some point you realize that we can and probably even have made penises in the lab.
Obviously it's not something that I think will happen soon, but it's inevitable that some more insecure about their size or erectile dysfunction sufferers are going to push through the idea of just surgically replacing their dick with a larger or more functioning model - one made from their own cells extracted and grown in a lab.
Again, inevitable, albeit a good ways off.
But it doesn't have to be limited to size, a dick made from your own cells could also be varied in shape, as the 3D printer or scaffold only needs to be set to place the cells in that shape. As long as it's merely structural and not reliant on some weird genetics, you could have a dick shaped like anything, including animal dicks. Dog dick, horse dick, horse dick with a dog's knot. Sky's the limit.
So, if this becomes available in the future, would you like to have a literal horse cock swinging between your legs, or a doggy dick to please your "bitch" (whether that's a female dog or your slutty submissive I'll leave to you)? What do you think about this possible future in general? And would it help the perception of zoophiles and bestiality if many men have upgraded their dicks with something more animalistic looking?
