Go midlane, and just practice. Getting your reflexes up for proper W timings is quite difficult to get used to, especially against quick skillshots like zed shurikens or something, but it comes with practice. Your first 15 ish games with yasuo will always feel strange and bad, you might get fed but end up losing lategame due to overestimating your damage and underestimating the opponents. Eventually it all just becomes second nature and yasuo becomes pretty easy. I recommend buying a 3rd or 4th defensive item so you don't die as much, it's very good. NEVER pick yasuo into a riven or darius, no matter what stage of the game they will both oneshot you unless you MAJORLY outplay them, and it's not worth it.
