Am I not looking after my underarms well?

For hygiene purposes, I regularly shave my armpits and pubic hair; I use a shaver and shaving cream to lubricate. After shaving I use after shave to disinfect and avoid rashes, but still, I experience rashes, itchiness that leaves behind blisters. I was once advised to use mentholated spirit to ease the itching and rashes but nothing has changed.
