Alright, so this one will probably be an easy one for some people. Although it could be tricky for others.
Take a guess and then read on to see if you’re right.
If you’ve ever seen photos from the hard galleries, this will probably be familiar to you. Oftentimes when men opt for heavy genital modifications, nullification and penectomies being the main ones, urinating becomes a problem. With this modification, the urethral reroute, they can continue work on their genitals and not have urination problems.
I picked this image in particular simply because it’s a great example of a clean, healed, reroute.
