So I've recently started shaving my area because my SO told me that he prefers it. He didn't force me to, said he liked me how ever, but I did it anyway.

So what I need help with is it has been 3 days since I shaved it and its all irritated, itchy and red bumps almost like little tiny pimples. They showed up about a day and a half after I first shaved.

How do I get them to go away and not come back when I shave again?
