Shaving

I’ve always shaved my pubic hair though no matter what I try I always get a shaving type rash it’s like little red bumps around the edge. I have honestly tryed different razors, coconut oil, using conditioner instead of soap and more. I was wondering if anyone would have any tips because my boyfriend and I of a few years would like to start doing more things but I keep pushing the issue freaking out that it could annoy him or me. So any tips would be greatly appreciated ❤️❤️.....
