Curious about Penis Bisection?

So, apparently people are starting with this form of body modification- penis bisecting (cutting your penis in half down the length pretty much), and i had a few questions (after being thoroughly disgusted/shocked/blinded etc.)
How do you pee or have sex with a penis bisection?? If you masturbate can you cum by jerking off one of the shafts or do you have to double fist it and do both?? And lastly. . . . ..
WHY THE FUCK WOULD YOU WANT TO CUT YOUR PENIS IN HALF!?!?!?!
. . .
thank you, that is all.
