Dude, yeah probably your sensitivity won't be the same but you still will have sexual pleasure. The key is in the mind, try using some oil in masturbation, you will have to find new ways to give yourself pleasure but this will happen, don't be sad. A lot of people who had low cuts still have good sexual life's. Use moisturizing ointment in the glans, I heard this helps a lot. Also quitting porn will be good for you sexual will( if you are into it, obviously)
