Why do older men find me more attractive?

Maybe you are just way more mature than your peers. Couple that with a young look and you are going to wind up attracting older guys. Nothing wrong with that by the way, you are over 18, an adult and so are they.

yes to your last 3 questions.

It's most likely your personality and how you look physically.

I think you answered your own question. Why do older guys go for you? Because you're attracted to older men. We're not that complicated, so it's a safe bet there's something in that dynamic that's causing this.

okay, one girl below stated that men want someone weaker, needy, dependent, etc. yes, that is true to a certain extent. No man wants a woman who can't do anything for herself and who is needy. You need to have a life of your own. YOu need to have goals, aspirations, dreams and etc. Being an independent woman, doesn't mean you have to pronounce to the world that you don't need a man. YOu can be an independent woman and still desire a man in your life. Yes, a guy wants to feel like a man, dominant etc, but he also doesn't want to feel like your daddy, always having to do everything for you. It gets old quick. If he senses he is the center of your entire world, ( meaning you have no life other than him) he'll get tired of you.
as far as why they date younger women or ( in this case the question asker) I feel that it probably first a physical attraction (but this will not keep him here) and later on your personality. A 30 something year old man with an established life and occupation doesn't want an immature 18 year old who plays with barbies and is emotionally unstable. Men don't like drama. More than likely if these older men are taking you seriously its because you have demonstrated that you are a WOMAN, not a little girl. There is a big difference between a little girl and a young WOMAN who is emotionally stable and mature enough to enter into a relationship with an older man.
yes to some extent younger women may look a little better in general, but that is not always the case or the reason for them talking to you.
If a man only dated me cause I was younger and my skin was tight, I wouldn't date him. What do you think he is going to do when you age. Yes, you answered correctly, look for another younger woman to have an affair with lol. But if there is a connection then its not all about looks , and you could have a lasting relationship. Being that you want a relationship, cause some girls don't.

i think it could be that you are mature for your age. You may carry yourself in a way that makes you seem older than what you really are. Most men are open to dating young women than women are to dating young men. It just society. So you would see more older men willing to give you a chance. A lot of older men date younger women, because they feel they are naive ( not stupid) but don't yet know all the tricks men have up their sleeves. This is a little different from easy to manipulate. All women are naive when they first begin dating, you learn from experience.
But being that I don't know you well it could be a number of reasons. It could just be that your mature for your age. I really can't tell you unless I met you.

It's hard to say without knowing you. Honestly it could be.

Older men always find younger girls attractive because they don't have wrinkles on their face, and are not saggy and full of loose skin. I'm an obese 22 year old and just about every older man that I meet online wants to date me.
