Why is it so hard looking younger than your age?

I love looking younger for my age. However it is very difficult when it comes to certain things. When I tell people I am 26 they just have the most shocked look. Everyone thinks I am between 16–19. I turn 27 in June. I was always this skinny small kid with a young face. Now I am a bigger more athletic guy with a baby face. Never was a ladies man in high school or college because I looked so young.

1— Underage kids will hit on you: It is so awkward. Can’t tell you how many times a High school girl tried to hit on me. I just ignore them and go about my business. I feel bad for ignoring them thou. Don’t want them to feel they are not pretty which all of them are. Once in a while they will take out a mirror or phone to check themselves out. To see if they are looking nice. They are all beautiful girls, just too young for me. I often ask where were girls like this when I was in high school?

2— Where ever I go people keep asking me what Highschool I go to. I’m also constantly getting stopped by cops because they think I am cutting class.

3— I look like the baby of the group when among friends my age.

4— Finding someone my age is so hard. Especially when I look like their little brother. Many women my age look so mature compared to me. I tried dressing more mature like, however it does not work.

5— You will be surprised how differently older people treat you when they think you are much younger.

Anyone else look younger than their age? How do you deal with these issues?
