I've not found any of the chemical depilatories that work on me without burning. For years I shaved until I found sugaring. Now I go to a local guy who sugars my back, butt, crack, taint and balls. Sugaring is a gentler form of waxing. If you still want to shave I'd say look for someone local. There are at least three folks offering "manscaping" on Craig's List in my area. You might also have a look at Double List if you don't see anything on CL.
Year's ago I found out that my local LMT would shave me if I brought the cream and razors. If you have a relationship with a local LMT you can ask. Note that licensing issues differ from state to state and LMT's might not be allowed to do this (legally) in your area. That's the case here in Oklahoma but if you have a good relationship with them anything is possible.
Currently I'm trying laser hair removal and like the results. We've had to pause the treatments as my all over tan is too dark for the laser to work well.
Good luck. I'd suggest testing any chemical on a small area as I have had significant reactions to the chemicals. I would also suggest a product called Finipil cream that is available on Amazon. It's an antiseptic cream that will help with razor burn or help to calm the skin after using chemicals or waxing.
