Iam afraid of getting old. I feel that my life is slowly slipping away. I would rather stay young. I feel attracted to 18 year olds...because they are young. I feel tortured by that aspect.
well, just keep in mind one more thing:
while an 18 year old may be attractive to you because she's young, you might want to think about the girl who wants to be with a man twice her age at such a time of being unformed and (is traditionally looked at as) a time of expression, learning about/finding one's self, developing independence and lots more milestones. milestones that have much to do with being free of expectations/commitment.
what does (or should) it tell you about the fact that she wants to be with you? in every situation that i'm aware of that resembles what you're describing has turned out to be a very young woman looking for a guy to be her dad. someone to protect her from what she's afraid of, or to escape from where she is. not a partner, but a parent.
i'm not saying that ALWAYS happens, but it's rather common.
and why is it that you "need" to feel young? what are you trying to escape from (or run towards)?
that feeling of youth is something that you never have to surrender, unless you choose to. you don't need a 18 year old gf for that....
i speak from experience on that one. : )
