Uncircumcised advice

Hey, I 22M just got my first cage and belt its metal and absolutely love it, however im uncircumcised so im faced with this problem; either my foreskin stays up to protect the sensitivity of the head and gets pinched between the tip of the cage and my underpants, or i pull the foreskin back and expose the sensitive head which when it comes in contact with my underpants or anything else can range from uncomfortable to painful but so can my foreskin pinching.

My question is, what is the best way for uncircumcised people to enjoy chastity, is there something I’m missing or should be doing different or something to get used to and over time will reduce?
