Questions about shaving pubic hair ?

everytime i shave my skin feel kinda itchy and irritated. I dont get razor bumps anymore, but its just always so irritated feeling for a few days. By the time it feels better i gotta shave again. Should i shave everyday? Will my skin evenyually get used to it? I and 24 and been shaving since i was a teen, so why would i not be use to it by now? Please help, any suggestions?
