I'm uncircumcised and when I discovered that there was a little treasure hidden under that skin I also quickly discovered that the head was extremely sensitive. So much so that I couldn't bare to even lay a finger on it when exposed. I did a little reading and porn watching and it occured to me that since most guys don't have that skin, overcoming that sensitivity was indeed possible. So I did that. I started by peeling the skin back (may need lube at first) and just lying in bed like that, not touching it but letting it be exposed to air and the skin of my belly as it just lied there. Eventually I worked myself up to touching and holding it (though gently). Then I would pull the skin back, put on underwear and pants, and walk around with it rubbing around in my undies. One day I went to school like that. Then I started touching it while masturbating. The rest is a blur but it took work and now I'm fine with it. I actually found that when fully hard it became less sentitive and easier to work with. Even still I prefer to be handled by my girl with the skin in place unless she's lubed up her hands a real real lot and during sex the skin comes back on its own and all is well. Lubing the inside of the condom a bit might help the comfort too. Also remember the foreskin will become more stretched out if you practice pulling it back so if it's too tight to be comfortable, just practice.

On a slightly different note, I've always wondered something. When I first exposed that skin to the world, it hurt. It was nestled in the foreskin and protected for so long. I wonder if that's how babies feel when born. Their skin has never had unlubricated touch. It's never been exposed to the elements and dried out. No wonder they cry and memory of those times is blocked out.
