I'm 22 and I look like I'm still in high school?

As u can tell I look much younger than I am, it doesn't bother me sometimes but other times I loath it. They always ask me for my Id usually when I buy cigs or alcohol but sometimes at the liquor store they check my ID really hard to see if it's fake when it's not which I can understand. The part I hate is that when I meat and talk to people in the outside world they ALWAYS assume that I'm in high school at 1st and like I usually date and hook up with girls that are younger than me (no one under 18) but like the closer they are to my age the less serious they take me I feel. I fucking hate it sometimes like wtf am I suppose to do?
