Most 30 year olds I have met that have been happy to be in relationships with teenagers have been unemployed bums, usually with drug problems. My hubby is 32. I know if he was single and had the chance he would happily sleep with an 18 year old but he would not have a relationship with her. Most single guys we know are looking to settle down and do the home and family thing, not entertain a teenager who is unlikely to really know what she wants yet. I'm not trying to put you down but look at it this way, how different were you when you were 6? The changes in those 12 years would have been different to the changes that someone experiences between 18 and 30, but none the less, the changes are significant. I bet when you were 6 you were dreaming of something completely different to what you are now. I'm sure there is very little that you do now that you did as a kid. By the time you're 30 the same thing will happen.
Don't be in such a rush to grow up. It seriously happens to fast as it is, and an older man that would date you is likely to try and make you grow up faster than natural. Enjoy your youth. Don't throw it away on an old man.
