Well I've been stretching my foreskin for about 2 weeks now, and have noticed a little progress. I can now see a lot more of the head, but as I had predicted it is SUPER sensitive. I can't even touch it, so I'm wondering what kind of cream or lube should I put on the head to make it less sensitive? Will it help the foreskin retract better if I use a lube or cream?

The sensitivity is normal. It will lessen as you expose it to more stimulation slowly. Are you stretching in a warm bath or shower. The soaking helps soften the foreskin and may help a little with the sensitivity problem. Exposing it to a shower spray is a good first step in getting it used to touch. A bit of olive oil or vitamin E cream may also help soften and/or lubricate when stretching. During sexual activity KY or other water-based lube may help.
