Just try baby lotion on your dick la. Do it everyday.

And when you bath, use the water hose with running water and cup it to your dick. It will fill the gap between dick head and skin. Do it everyday for few minutes.

As my family is in steel business, sometimes I suffer from foreskin dryness whenever I had to cut steel due to worker shortage. Exposed to heat, sometimes make the foreskin dry and tight. Even tore the foreskin a few times especially when wearing condom which could take weeks to heal. Using lub during sex also help with dry and tight foreskin.
