Trying to understand if my dick is fried

It's gonna sound like a stupid question but I'm trying to understand if my dick is broken beyond repair or I'm just in need of a very long no fap. My question is, are you supposed to feel pleasure when your tip is tickled, or is it fine for it to just feel being touched anywhere else in your body?

The reason I'm slightly kinda worried is because I fap dry, and I've had times where I was doing it so much consecutively that lacerations did start to appear on my head from all the tugging and stretching of the dry skin. Skin would peel off, scabs would form and eventually it would heal over time

But that stopped like over a year ago, I've been doing after care since with Vaseline. Point is though, I noticed that when I tickle the tip of my penis it doesn't really do anything for me compared to when jerking off regularly. And I'm wondering if this is because I fap too much and so it takes greater stimulation to do something for me, or is it because of how aggressive I used to be to the point of injury, and so my nerve endings are just permanently fucked. I don't know if regaining my touch is a goal to aim for, or never having it again is just the punishment I have to live with for my addiction. I'm also circumcised so
