Dear b3xyb33,
Don't be in such a big hurry to grow up - be a kid for a few more years - believe me when I tell you that as you do grow up, you will long for the days of childhood, and be scorned and ridiculed when you try to have like you used to as a child.
Now, as to this 18 year old boy. The only appropriate relationship for a 14 year old and an 18 year old is as friends, or as a 'big-brother/mentor' role. It may seem like you are only 3-4 years difference in your ages, so what's the big deal, but the is a world of difference between a 14 yr old and an ADULT of 18. He can vote, he could be drafted and forced to choose between killing other human beings in a war or go to jail if he refuses. In every state in the US, and many countries around the world, he would be convicted and spend 20-30 years in year if you admitted that he had sexual relations with you. It wouldn't even have to be true. It would happen even if you forced yourself upon him. At your age, the law states that you DO NOT have the rational ability to decide if having sex is good or bad for you. Even if you think it would be the best thing in the world, and that you would literally DIE if you did not have sex, the law states you do NOT have the right to decide.
The internet can be a great place to get to know someone. If you want to be friends with this young man, spend the next four years of your life learning how to express yourself and effectively communicate by getting to know him via eMail.
Then, if in the day you turn 18, you think the best thing in life is for you to 'have a relationship' with him, you will then be able to without risking 20-30 years of his life and liberties. Besides, when you are 18, and he is 22, there won't be nearly as many differences between you as there are now.
Life flies by my young friend, it seems like it was just the other day when I was 14 and had sweaty palms and was obsessed with a 14 year old classmate. I was firmly convinced she was the love of my life and we would grow old and grey together. She moved three states away the next summer and 40+ years later, I have not heard from nor seen here, ever again.
And was I in love, I can still feel the aching depth of my love for her.
THAT is what makes us persevere as human beings, in spite of the pain life deals us daily.
Be smart, please.
