I've had plenty of sex but I still don't feel like an adult. I'm 28 and I still laugh at things like south park and flooding /vip/ with JEWS.
On the other hand I also read a lot so I'm not a total buffoon.
I can understand your thinking on sex and adulcy, but really after the age of about 25 you still don't feel like an "adult". I think it's because when you were a child, adults seemed like invincible beings, almost alwayds frequently right, and in no pysical danger. Not many people grow up to this expection. That's ok though. As long as you've got a good mind to keep you from geetting totally bored you shouldn't feel too bad.
