Sorry , your text is unreadable but it seems as if you want to do that for real.
Of course cutting your lower half is not good idea as in that case playing with your tits or licking pussy will be the last thing to do, but you could feel same with just local anesthesia as on how it is not to have half of your body. Only difference is that you woud not be able to lick your pussy but otherwise it should be same feeling.
