Researchers have been able to grow new penises for rabbits in experiments in the states. This coms from the same researchers who have been growing and implanting such things as new bladders.
I suppose this means that in the future there will be an entire legion of gay men going off to their surgeons for the penis of their choice.
I can just imagine it now, instead of gay men looking and drooling over porn they could ask for an engineered fully functional penis of the size and shape of their choice.
Can you imagine on gay dating sites it would no longer be the size of the penis it would be 'whose penis have you copied'
