Sup guys, need some help.

I'm 27, 5'8, 154 lbs and a very very baby face. i workout for 2 years now and it DID help, but the face is still here and baby. Beard is out of the question ofcourse, since i still didn't pass the teenage moustache.

So the issue is so "severe" that people i meet (both male and fe) almost always tend to comment on my looks, just this weekend i was at a house party with some people i just meet, and this one girl (we didnt even have a conversation yet) feelt the need to publicly comment on me and ask questions. And it happens pretty much in every interaction with new people. I can't get people to take me serious, as in "im not fucking retarted because i look like a 19yeard old", and if i try to guard my "reputation" there is always someone else who will then comment on my not only baby face, but also lack of beard and shot me down completly.

Now i do and i don't get upset about this, depens my day pretty much. But the question is, how do i handle situations like that?

Sometimes i just wanna slap the shit out of these people. Sometimes i just brush it off. But my public image is in the toilet everytime it's brought up. And it's even worse because my face is very very reactive to my state of mind, so you can assume i get blushy and it shows on me very very much.

I accepted that im baby face'd (hopefully a very late bloomer) but the fact is im a 27 yeard old who still can't buy cigarettes.

If you feel the need to respond with "lol lucky you, you will bang in your 50's" or something like it, please spare me.
