There's no greater source of technological embarrassment than when iPhone autocorrect goes terribly wrong. All you have to do is Google 'embarrassing autocorrect' and you'll be presented with a lifetime supply of cringe-worthy stories. The worst part is that you don't actually want to turn autocorrect off, as it does tend to help more than it hinders.
Here's a solution you can try. Instead of deactivating autocorrect or allowing it to embarrass you, you can head to Settings > General > Keyboard and change your text replacement settings. You can also hook up some time saving replacements while you're there. For example, 'OMW' can be autocorrected to 'on my way'. Try to think of the words and phrases you use most and add shortcuts so you'll never have to type them out in full again.
